The present invention aims to ensure luminosity while improving evacuation characteristics in a plasma display panel. First ribs () that separate a plurality of cells from each other and second ribs () are formed in stripe patterns so as to intersect with each other on a surface of a first substrate (), a surface of a second substrate opposes tops of the first ribs, and a height of the ribs at intersections () of the first and second ribs intersect is lower than other parts of the first ribs ().

Plasma display panel and manufacturing method therefor

A substrate for use in crystallization has a base member, and an organic molecular film on a surface of the base member. The organic molecular film has non-affinity to a liquid, and the surface of the base member and the organic molecular film are covalently bound to each other. The substrate formed with the organic molecular film having non-affinity to the liquid on the surface of the base member is produced by contacting the surface of the base member having an active hydrogen atom or the surface of the base member to which the active hydrogen atom is introduced, with an organic molecule including a terminal-bonding functional group capable of covalently bonding to the surface of the base member at one end thereof, and a functional group showing non-affinity to the liquid at the other end thereof so as to covalently bond the terminal-bonding functional group of the organic molecule to the active hydrogen atom on the surface of the base member by reaction of the terminal-bonding functional group with the active hydrogen atom. The substrate enables to efficiently crystallize polymeric compounds including biomolecules such as proteins, nucleic acids, and sugars; and resins, as well as other organic compounds, and inorganic compounds.

Substrate for use in crystallization and method for producing the same

A plasma display device that enables a stable address operation even in a high-speed drive so as to display an image of high definition and high quality. A PDP having discharge cells each provided with a scanning electrode and a sustaining electrode is driven by a method for displaying a frame of an image by repeating an address period, a discharge sustaining period, and a discharge suspend period. At least one initialization period that succeeds a discharge suspend period and in which the state of the wall charge in each discharge cell is initialized is provided. In the discharge suspend period, a voltage is applied between the scanning electrode and the sustaining electrode so that a wall voltage may be generated at which the polarity at the scanning electrode with respect to the sustaining electrode is the same as that of the initializing pulse applied to the scanning electrode in the initialization period.

Plasma display device and method of driving the same

Plasma display and its driving method

A discharge panel capable of high-quality display by preventing erroneous discharge between adjacent lines in a sustaining electrode or the like. A sectional shape in a direction orthogonal to the longitudinal directions of both a first display electrode () and a second display electrode () has a stepped shape, a film thickness of a discharge gap (Gap) side portion is greater than that on a non-discharge gap side, the film thickness of the respective steps being specified as L, L, L(L&#x3e;L&#x3e;L). Accordingly, a discharge start voltage on the discharge gap side is lower than that on the non-discharge gap side even when the discharge gap and the non-discharge gap have the same width geometrically, thereby reducing erroneous discharge between adjacent cells positioned on an adjacent lines.

It is the object of the invention to provide a PDP apparatus and a driving method that can apply pulses at high speeds and can display high-definition, high-quality images by allowing discharge cells to emit light with high luminance and high efficiency. To achieve the object, the pulse has (i) a first waveform portion where a first voltage, an absolute value of which is no smaller than a discharge start voltage, is applied and (ii) a second waveform portion where a second voltage, an absolute value of which is greater than the absolute value of the first voltage, is applied, the second waveform portion following the first waveform portion, and the second waveform portion starts before a discharge delay time elapses from a start of the first waveform portion. Also to achieve the object, in a PDP having an electrode structure in which each electrode is divided into a plurality of line electrodes, the applied pulse has (i) a first waveform portion where a first voltage, an absolute value of which is no smaller than a discharge start voltage, is applied and (ii) a second waveform portion where a second voltage, an absolute value of which is greater than the absolute value of the first voltage, is applied, the second waveform portion following the first waveform portion.
