    摘要： 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.

    摘要： A color display pixel PCD in a liquid crystal display device (100) includes first through fourth pixels P1 through P4 arrayed in two rows by two columns, and first and second signal lines (13a, 13b) which are located in correspondence with each column of pixels and are supplied with signal voltages of polarities opposite to each other from a signal line driving circuit (30) in each vertical scanning period. A TFT (14) of one of the first and third pixel P1 and P3 is connected to the first signal line (13a), and a TFT (14) of the other pixel is connected to the second signal line (13b). A TFT (14) of one of the second and fourth pixel P2 and P4 is connected to the first signal line (13a), and a TFT (14) of the other pixel is connected to the second signal line (13b). The TFTs (14) of the first through fourth pixels P1 through P4 are controlled to be ON/OFF by a common scanning signal, and the polarities of the signal voltages supplied to the first and second signal lines (13a, 13b) are constant during an arbitrary vertical scanning period. Owing to this, the load on the signal line driving circuit is reduced.
