A plasma display panel comprises a front substrate and a rear substrate, a plurality of row electrode pairs provided on the inner surface of the front substrate, a dielectric layer provided on the inner surface of the front substrate for coverring the row electrode pairs, a plurality of column electrodes provided on the inner surface of the rear substrate, a partition wall assembly provided between the front substrate and the rear substrate, said partition wall assembly including a plurality of longitudinal partition walls and a plurality of lateral partition walls, forming a plurality of discharge cells. In particular, the dielectric layer has a plurality of projection portions located corresponding to and protruding toward the lateral partition walls of the partition wall assembly, in a manner such that there would be no slots formed between the dielectric layer and the lateral partition walls.

Plasma display panel

A plasma display panel includes: a plurality of row electrode pairs (X, Y) provided on a front glass substrate (); a protective layer () on the front glass substrate (); and a plurality of column electrodes (D) provided in a back substrate () at intersections with the row electrode pairs (X, Y) to form discharge cells (C) in the discharge space (S). An ultraviolet region light emissive layer () having persistence characteristics allowing continuous emission of ultraviolet light as a result of excitation by ultraviolet rays having 0.1 msec or more of a wavelength is provided at a site facing each discharge cell (C) between the front glass substrate () and the back glass substrate ().

Plasma display panel that inhibits false discharge

In a surface-discharge-type alternating-current plasma display panel, a discharge cell is divided into two cells: a display discharge cell C providing for a sustaining discharge between transparent electrodes Xa, Ya of row electrodes X, Y; and an addressing discharge cell C which is opposite a bus electrode Yb of the row electrode Y, giving rise to an addressing discharge in association with a column electrode D, to provide for the addressing discharge between the bus electrode Yb of the row electrode Y and a column electrode D. The display discharge cells C and the addressing discharge cells C of the discharge cells are interposed in alternate positions in the column direction so as to arrange the addressing discharge cells C in a back-to-back position in the column direction.

In a plasma display panel, a partition wall surrounds each of discharge cells to define the discharge cells. Each of the discharge cells is divided by a second transverse wall B into a display discharge cell C which is opposite transparent electrodes Xa, Ya of paired row electrodes X, Y to provide for a sustaining discharge; and an addressing discharge cell C which is opposite a bus electrode Yb of the row electrode Y to provide for an addressing discharge caused between the bus electrode Yb and a column electrode D. A clearance r is provided between the discharge cell C and the addressing discharge cell C for communication between the cells C and C

A plasma display panel includes a plurality of row electrode pairs (X, Y) forming display lines which are formed on a front glass substrate ( ). Each row electrode (X, Y) of the row electrode pair (X, Y) makes up transparent electrodes (Xa, Ya) each formed opposing the corresponding transparent electrode (Xa, Ya) via a discharge gap (g) for each pair, and a bus electrode (Xb, Yb) connected to the transparent electrodes (Xa, Ya). In such plasma display panel, a light-shield layer A is formed at least on a portion between the two bus electrodes situated back to back and a required portion in proximal to sides of the bus electrodes (Xb, Yb) connected to the transparent electrodes (Xa, Ya) on the front glass substrate ( ).

Plasma display panel and method of manufacturing the same

A plasma display panel includes a front substrate and a rear substrate, a plurality of row electrode pairs provided on the inner surface of the front substrate, a dielectric layer provided on the inner surface of the front substrate for coverring the row electrode pairs, a plurality of column electrodes provided on the inner surface of the rear substrate, a partition wall assembly provided between the front substrate and the rear substrate, said partition wall assembly including a plurality of longitudinal partition walls and a plurality of lateral partition walls, forming a plurality of discharge cells. In particular, the dielectric layer has a plurality of projection portions located corresponding to and protruding toward the lateral partition walls of the partition wall assembly, in a manner such that there would be no slots formed between the dielectric layer and the lateral partition walls.

A plasma display panel has a pair of substrates including a display side substrate and a back side substrate, a pair of opposed row electrodes disposed inside the display side substrate interposing a discharge gap, each of the row electrodes comprising a transparent conductive film and a metallic film formed on the transparent conductive film at a position opposite to the discharge gap, a dielectric layer covering the row electrodes. The dielectric layer includes a first dielectric layer formed on the inner surface of the display side substrate, a second dielectric layer formed on the first dielectric layer except the discharge gap and a third dielectric layer formed on the first and second dielectric layers.

In a plasma display panel, studs or second ribs are provided on the inner surface of a back side substrate. Each stud faces an edge portion of the associated one of projecting portions of the associated one of pairs of row electrodes far from a discharge gap therebetween and faces the associated one of body portions of the associated pair of row electrodes in the vicinity of the associated projecting portion. The studs are designed to be in contact with the dielectric layer.

Plasma display panel with first and second ribs structure

An optical recording medium comprises a baseplate and a record film, on which information is recorded,disposed on the base plate, the record film containing 5-dimethylamino indolyl fulgide, of the specific formula, and a resin binder. The information recorded in the optical recording medium is reproduced by irradiating a first light to the record film, the first light being absorbed by 5-dimethylamino indolyl fulgide in an open ring form, whereby the open ring form is changed to a closed ring form and information is recorded and irradiating a second light to the record film in which record is recorded, the second light having zero of quantum yield in changing the closed ring form to the open ring form and being absorbed by the closed ring form, whereby the recorded information is reproduced.

Optical recording medium

An optical disc has a recording film with information recorded thereon, and a photochromic material film provided adjacent the recording film. The photochromic material film is made of a photochromic material. The photochromic material has a first state irradiated with reading light having a first wavelength. In the first state, the transmittance of the material is increased so as to enable reading of the recorded information. The photochromic material further has a second state irradiated with auxiliary light having a second wavelength, where the transmittance becomes low so as to disable the reading of the recorded information.

Optical disc and optical system for reproducing the optical disc

A rewritable photochromic optical disc which comprises a photochromic recording layer made of a diaryl ethene derivative capable of assuming first to third states, the first state with a first absorption band transforming into the second state with a second absorption band in response to light of a first wavelength, the second state transforming into the first state in response to light of a second wavelength in said second absorption band, the fist state transforming into the third state with a third absorption band in response to light of a third wavelength, and the third state transforming into the first state in response to light of a fourth wavelength in said third absorption band.
