发明名称 Liquid crystal display
摘要 A liquid crystal display is disclosed. The liquid crystal display includes a data driving circuit, that converts digital video data into positive and negative data voltages, supplies the positive and negative data voltages to data lines of a liquid crystal display panel, and causes the data voltages supplied to the same data line to have the same polarity during one frame period, and a gate driving circuit sequentially supplying a gate pulse to gate lines of the liquid crystal display panel. Subpixels of the liquid crystal display panel include first and second subpixels positioned adjacent to each other in a horizontal direction. Each of the first and second subpixels is successively charged to the data voltages of two colors.
