Active matrix liquid crystal display device having discharge elements connected between input terminals and common terminal |
摘要 |
A liquid crystal display device of the active matrix type which prevents residual of charge in liquid crystal picture elements with respect to time. The active matrix liquid crystal display device includes liquid crystal picture elements formed from a liquid crystal layer held between picture element electrodes arranged in a matrix and common electrodes opposing to the picture element electrodes, and picture element transistors corresponding to the liquid crystal picture elements. While a predetermined reference potential is supplied to the common electrode, image signals are applied to the individual picture element electrodes by way of signal lines and picture element transistors to effect ac driving of the liquid crystal picture elements. Discharge means for connecting the common electrodes and the picture element electrodes to an equivalent potential to each other is provided to discharge the charge remaining in the liquid crystal picture elements thereby to prevent the variation of the reference potential.
