Liquid crystal display device |
摘要 |
The present invention realizes a liquid crystal display device which forms a miniaturized low dielectric strength drive circuit on a substrate on which a display part is also formed. Apart from a drive circuit which supplies gray scale voltages to pixels, a circuit which lowers the pixel potential and realizes alternating driving is provided. Signals of positive polarity are written in a pixel electrode and, after writing, the potential of the pixel electrode is lowered using the capacitance connected to the pixel electrode. Further, between the circuit which lowers the pixel potential and a display region, a pull-up circuit for assisting off-switching is provided for reducing rounding of waveforms of scanning signals is provided.
