A display device includes an optical region containing a plurality of pigment grains. Each of the plurality of pigment grains formed by a plurality of pigment molecules encapsulated in an inorganic material, and each of the plurality of pigment grains has a grain size not greater than 70 nm.

Display device

In a display device comprising an optical region containing a plurality of pigment grains utilized for wavelength selection, anti-reflection, improvement of the light emitting performance and the like, dyestuff molecules utilized for forming the pigment grains to be dissolved in a solvent in which the dyestuff molecules are insoluble originally are chemically modified, and then the solubility of the modified dyestuff molecules in the solvent is reduced by energy transfer thereto to aggregate the dyestuff molecules, so that grain sizes of pigment grains are suitably controlled for the optical region in accordance with its use.

A high definition display apparatus having a wavelength selective absorption effect and an anti-static and anti-reflection effect is provided by thin films having a low resistance and a high refractive index. The high definition display apparatus has an anti-static and anti-reflection film composed of laminated oxide or metallic thin films, wherein at least three layers of oxide or metallic films having different reflectance from each other are laminated onto the front surf ace of the display apparatus, and the laminated films are composed such that an absorbing film containing coloring material is arranged under a high reflectance film as seen from the outer surface of the laminated films.

A ferroelectric element having a high Pr and a low Ec and having a good withstand voltage, which is in the form of a thin film using a ferroelectric layer containing insulating particles, is provided. The ferroelectric layer containing the insulating particles is effective to suppress leakage current caused through grain boundaries of crystals, and hence to exhibit a high Pr and a low Ec and a good withstand voltage. The ferroelectric element has a structure in which such a ferroelectric layer in the form of a thin film is sandwiched between electrodes. By incorporating the ferroelectric element in a field effect transistor structure, it is possible to realize a highly integrated semiconductor device for detecting reading or writing.

A cathode ray tube includes a film which is formed on an outer surface of a panel portion. The film is comprised of a first particles which become transparent due to the oxidation and a second particles which are chemically and physically stable and have the light absorbing ability and the conductivity. A number of the transparent first particles is gradually increased toward a peripheral portion from the center portion of the panel portion.

A display device substrate which meets requirements for weight reduction, thickness reduction, high reliability, good heat resistance, and good impact resistance all at once. The display device substrate is composed of a pair of glass sheets facing each other and a layer of plastics material interposed between said paired glass sheets in such a way that said glass sheets have an internal compressive strain ascribed to the plastic sheet. Thus, the very thin glass sheets are hardly liable to breakage. This makes light weight and reduced thickness compatible with reliability.

A method of treating a metal alkoxide solution to form metal oxide prepolymer molecules therein is characterized by irradiating the solution with light energy having a wavelength selected to break the metal-alkoxy group bond in said metal alkoxide, thereby to form the metal oxide prepolymer molecules in the solution. The prepolymer is converted into polymeric metal oxide gel. The stoichiometry of the oxide is high. A gel of carbon content below 4 atomic % can be achieved by the step of decarbonizing the gel, preferably using light to produce ozone.

An anti-reflection film is in the form of a laminated film composed of an uppermost film layer containing coloring matter having an absorbing peak in a region near the infrared region of 700 nm-900 nm, or coloring matter having an absorbing peak in a region of 600 nm-700 nm, or both of the above coloring matter, and the next film layer to the uppermost layer containing coloring matter having an absorbing peak in a region of 500 nm-600 nm. The anti-reflection film utilizes a variation of the refractive indexes based on abnormal refractive index dispersion by the films containing the coloring matter. The anti-reflection film having a low reflectivity all over the visible light region can be manufactured by utilizing the abnormal refractive index dispersion of the next layer to the uppermost layer caused by an absorption of red coloring matter and a balance with the refractive indexes of the uppermost layer containing red color matter having an absorption in the region near the infrared wavelength, or blue coloring matter, or both of the above coloring matter. Furthermore, red coloring matter, having an absorbing peak in the region of 500 nm-600 nm and contained in the next layer to the uppermost layer, absorbs side bands of green and red, and accordingly, color purity is improved.
