摘要:
A drive method of an information display panel, in which display media is sealed in a space between the substrates, at least one of which is transparent, and an electric field is applied to display media by application of a pulse voltage between electrodes provided each of the substrates opposed one another so as to display information such as an image, is to lower the pulse voltage by setting a circuit between the electrodes, to which the pulse voltage is applied, a high impedance state. Thereby, it can provide the drive method of the information display panel capable of achieving high contrast.

A color filter is provided with red, green and blue color filter segments. When chromaticity coordinates (x, y) in a chromaticity diagram of XYZ color specification system are measured with the color filter being sandwiched between two polarizers, a chromaticity (xp, yp) of parallel-transmitted light and a chromaticity (xc, yc) of orthogonal-transmitted light satisfy the following formula (1): Δxy=[(xp−xc)2+(yp−yc)2]1/2
摘要:
A colored composition contains a colorant carrier including a transparent resin, a precursor thereof, or a mixture of the transparent resin and the precursor, a colorant, and an organic liquid medium. The organic liquid medium consists of an organic solvent (a) having a boiling point at 760 mmHg of 100° C. or higher but lower than 160° C., and an organic solvent (b) having a boiling point at 760 mmHg of 160° C. or higher but lower than 215° C. The organic solvent (b) is contained in an amount of 3% to 35% by weight based on the total amount of the colored composition.
摘要:
A blue colored composition for a color filter contains a pigment carrier comprising a transparent resin, a precursor thereof or a mixture thereof, a blue pigment having a specific surface area of 90 to 140 m2/g, and a violet pigment having a specific surface area in a range of 100 to 150 m2/g, but having a greater specific surface area than that of the blue pigment used. A color filter includes a filter segment formed from the blue colored composition.
摘要:
There is provided a high luminous light conductive plate where concave dots formed on the surface of a resin sheet deflect light introduced from a light source to the interior of the light conductive plate so as to diffuse light into an extensive range with a roughened wall surface of the concave dots. An annular projection that flanges the peripheral end portion of each concave dot substantially increases the depth of the concave dots expanding an area contributing to the deflection of the concave dot. The concave dot formed on the surface of the resin sheet is formed by pressing a plurality of concave projections of a press die on the surface of the resin sheet through a cold process.

A vehicular air conditioner includes cabin-exterior fans that blow air with respect to a cabin-exterior heat exchanger in which a coolant is vaporized, and a plurality of openable/closable shutters disposed in a duct that communicates between the cabin-exterior heat exchanger and the exterior of the vehicle. On an upper portion of the duct, a cover is formed that covers the cabin-exterior heat exchanger, which is disposed rearwardly of the shutters, and an upper region of the radiator. Additionally, air that is raised in temperature by heat from the engine passes between the cover and both the cabin-exterior heat exchanger and the radiator, and is guided toward a forward side of the vehicle.
摘要:
A color filter adapted to be employed in an in-plane switching mode liquid crystal display device, which is incorporated in the liquid crystal device without interposing electrodes between a liquid crystal and pixels, and which includes a transparent substrate, and pixels having color layers representing a plurality of colors and formed on the transparent substrate, wherein a protective layer is not formed on the pixels, and a dielectric loss tangent (tan δ) of at least one color layer is confined to not higher than 0.03 at a frequency ranging from 10 Hz to 100 Hz.
摘要:
An article having a water-repellent fluororesin surface and a method for manufacturing the same, wherein the article has a water-repellent fluororesin surface composed of an irregularly porous material which has a maximum IPA diffusion diameter of at least 8 mm and is formed by irregularly stacking fluororesin particles with an average diameter of no more than 40 microns over one another and has a water droplet roll angle tangent of no more than 50/500. The obtained article has a fluororesin surface which exhibits excellent water-repellency, inhibits adhesion of water drops and soil entrained by the water drops and imparts a great bond strength to the substrate.
