摘要:
A plasma-addressed liquid crystal display device comprises a builtup structure including an upper glass substrate (1), a transparent dielectric sheet (2) brought into intimate contact with the upper substrate (1), and a lower glass substrate (3) disposed in face-to-face relation with the dielectric sheet (2). The upper glass substrate (1) has a plurality of data electrodes extending along one direction on the inner surface thereof. A plurality of discharge channels (7) extending along a direction intersecting the one direction is formed between the lower side of the dielectric sheet (2) and the lower glass substrate (3).
摘要:
A liquid crystal cell and a plasma cell are layered together with a dielectric sheet in between. Data electrodes (105) (column electrodes) are constructed to form parallel columns on the underside of an upper substrate (104) in a display cell. Discharge channels (112) filled with ionizable gas are constructed in parallel rows in a plasma cell. Row electrodes (131) are constructed on the upperside of a lower substrate (108) corresponding to each of the discharge channels, and reference electrodes (135) to which reference voltages are applied, are constructed inside each of the discharge channels. Data voltages are applied to the data electrodes and drive pulses are applied to the row electrodes. The polarities of the data voltages are changed so as to be opposite to the polarities of the drive pulses with respect to the reference voltages. Each time the polarities of the drive pulses are inverted, plasma discharges are generated in the discharge channel corresponding to the row electrodes to which the drive pulses are applied.

With the liquid crystal display provided by the present invention, the display contrast is improved by suppressing the reflection of an external light by a light diffusing layer employed in the liquid crystal display. The liquid crystal display comprises a liquid crystal panel 1, a directional backlight 2 and a light diffusing means. The liquid crystal panel 1 is of the transmission type having a front face and a back face on the side opposite to the front face. A polarizing plate 4 is placed in front of the front face of the liquid crystal panel 1. The backlight 2 is placed on the back side of the liquid crystal panel 1, providing all but parallel incident illumination light beams to the liquid crystal panel 1. The light diffusing means is placed on the front side of the liquid crystal panel 1, diffusing and emitting the incident illumination light beams leaving the liquid crystal panel 1. The light diffusing means comprises a light diffusing layer 9 and transparent filler stuff 10. The light diffusing layer 9 is made up of transparent fine particles 9a spread all over the gap between the front face of the liquid crystal panel 1 and the polarizing plate 4. The transparent filler stuff 10 is used for filling up gaps among the transparent fine particles 9a. The transparent fine particles 9a each have a refraction index different from that of a glass plate 3 constituting the front face of the liquid crystal panel 1 while the transparent filler stuff 10 has a refraction index close to that of the glass plate 3.
