段を設けたことを特徴とする液晶表示装置。[Claims for Utility Model Registration] A liquid crystal panel in which pixels in a dot array connected to orthogonal locations of scanning electrodes and data electrodes are arranged in a matrix, and red and green pixels are arranged in vertical stripes for each pixel. , a liquid crystal display device comprising: a color filter of three primary colors of blue; a data driver that supplies a data signal corresponding to a video signal to the data electrode; and a scan driver that supplies a scan signal to the scan electrode. Each pixel is constructed by arranging 3 dots in the horizontal and vertical directions with an aspect ratio of 1:1, and each pixel is composed of 3 sub-pixels with the red, green, and blue color filters. The image signal is divided into three parts, the video signal is converted into pixel data of multiple bits, and specific bits of the pixel data are used to control the gradation level of the sub-pixel, and other bits are used to control the brightness. A liquid crystal display device characterized in that it is provided with sub-pixel control means for performing.
