In an image display apparatus using an FED or an organic EL element, image display that is high in illumination uniformity and high in image quality can be performed. A display element with a matrix structure which conducts linear sequential driving which determines the luminance by a current is used, a threshold voltage of a cathode line immediately before one select period has been terminated where a control electrode line is sequentially driven is measured by a threshold voltage measuring section, the measured threshold voltage is recorded for each of the pixels, and a driving signal at the time of selecting the pixel is corrected by using the value of the recorded threshold voltage, to thereby control electric charge that is emitted from a cathode.

摘要:
Transparent conductive films produced by a series of steps comprising a coating step in which a solution obtained by dissolving an indium compound and a tin compound in an organic solvent is coated on a substrate; a preliminary drying step in which the coated substrate is dried at a temperature of 35.degree. to 100.degree. C.; a temperature rise step in which the coated substrate is heated at a temperature rise rate of 20.degree. C./min or more up to 400.degree. C. or higher; and a calcination step in which the coated substrate is calcined at a temperature of 400.degree. C. or higher, or by repeating said series of steps two or more times, have excellent properties such as strong adhesive strength to a substrate, excellent transmittance and remarkably low sheet resistance.
摘要:
In an active matrix type liquid crystal display apparatus, respective ones of the electrodes on a substrate are provided so that an electric field substantially parallel to the substrate can be supplied to a liquid crystal layer. Polarizers for changing the optical characteristics based on the alignment of the liquid crystal layer are provided, as well as a shielding layer formed in parallel to the image signal electrodes on the substrate. The specific resistivity of the shielding layer is less than 10.sup.8 .OMEGA..multidot.cm.
摘要:
Even when a high potential such as of static electricity is applied from the outside of the liquid crystal display panel, the display image is prevented from becoming abnormal. When a black matrix of a resin composition having a large resistivity is used, the positions of the polarizer plates, black matrix, sealing portion and open region of the housing are defined to prevent the light from leaking through the periphery of the effective pixel region. The leakage of backlight that cannot be prevented by the black matrix only is prevented by the polarizer plates and the housing, a transparent electrically conductive film having a sheet resistivity of not larger than 2.times.10.sup.4 .OMEGA./.quadrature. is formed over, under, or inside the polarizer plate, and the electrically conductive film is electrically connected to the electrically conductive housing.
