Abstract

A liquid crystal display device according to the present invention includes: a plurality of pixels that are arranged in rows and columns so as to form a matrix pattern; and TFTs (TFT-A, TFT-B and TFT-C), source bus lines, gate bus lines and CS bus lines (CS-A and CS-B), which are associated with the respective pixels. Each pixel includes at least three subpixels (SP-A, SP-B and SP-C) with liquid crystal capacitors that are able to retain mutually different voltages. By supplying a signal (CS-A or CS-B) that makes two of the at least three subpixels display mutually different luminances at least at a certain grayscale tone from the source, gate and CS bus lines to each pixel, the at least three subpixels are able to display mutually different luminances.
