Title: Liquid crystal display device
Inventor: ITO KATSUHIRO
IPC: G02F1/1365
Filed: 1988-09-29
Abstract: PURPOSE:To obtain the device which has high luminance and generates less crosstalks by disposing electrodes in such positions where the electrodes do not face the varistor disposed on the other substrate. CONSTITUTION:The picture element electrodes 12, signal lines 13, and the varistor films 14 constituting mainly of varistor powder are formed on the substrate 11a. On the other hand, the scanning electrodes 15 are disposed on the substrate 11b so as to face the electrodes 12. The parts of the electrodes 15 which face the films 14 are notched to prevent the opposition of the electrodes 15 and the films 14. The flow of current from the signal lines 13 via the films 14 to the electrodes 15 is obviated even under a high pressure and the normal matrix circuit of the liquid crystal and the varistor is formed. The crosstalks are, therefore, hardly generated even in case of using a polymer dispersion type liquid crystal of a high operating voltage and the display with the high luminance and high contrast is possible.
