Abstract:
1. A liquid crystal display device comprising: a plurality of liquid crystal pixels arrayed substantially in a matrix; a vertical driving circuit that selects rows of the liquid crystal pixels for video signal writing and for non-video signal writing; a horizontal driving circuit that writes a video signal in the liquid crystal pixels of a row selected for the video signal writing and a non-video signal in the liquid crystal pixels of a row selected for the non-video signal writing; and a control circuit that the vertical driving circuit is configured to set a selection pattern for disabling any overlap between a selection period of selecting the liquid crystal pixels of each row for the video signal writing and a selection period of selecting the liquid crystal pixels of any other row for the non-video signal writing, based on the control signal from the control circuit, the liquid crystal pixels constitute a display panel together with a plurality of gate lines which are arranged along the rows of liquid crystal pixels and a plurality of pixel switching elements which are arranged near the liquid crystal pixels, and are turned on to allow the horizontal driving circuit to perform writing to the liquid crystal pixels of a selected row when the gate line corresponding to the liquid crystal pixels of the selected row is driven, and the vertical driving circuit includes
