Lcd display with pixels having rgbw sub-pixels and where power consumption is reduced by using a polarity inversion pattern in which all red sub-pixels in a column have the same polarity

Abstract

Each image signal line S is connected alternately to a plurality of sub-pixels P positioned on one side of the image signal line S and a plurality of sub-pixels P positioned on the other side. During one frame period, image signals having either one of the positive and negative polarities are input to the first, third, fourth, and sixth image signal lines S, S, S, and Sof the eight image signal lines Sto Sthat constitute a unit array of the image signal lines during one frame period, while image signals having the other polarity are input to the remaining image signal lines S, S, S, and S. According to this liquid crystal display device, it is possible to prevent flicker in image and to prevent the common electrode position from becoming different from the base potential, while preventing increase of power consumption.
