Abstract:
1. A liquid crystal display device comprising: a source signal line over a substrate; a gate signal line over the substrate; a source signal line driving circuit; a gate signal line driving circuit; and a pixel over the substrate, the pixel comprising: wherein the pixel electrode and the gate signal line are formed on the same insulating surface, wherein the liquid crystal is provided over the pixel electrode and the gate signal line, wherein a first voltage is applied to the gate signal line at a gate signal line selecting period in a frame period in a time of display, a second voltage is applied to the gate signal line at a gate signal line non-selecting period in the frame period in the time of display, and a third voltage having the same polarity with the first voltage is applied to the gate signal line in an entire frame period in a time of non-display, and wherein a clock pulse supplied to the source signal line driving circuit and the gate signal line driving circuit is stopped during the time of non-display.
