Abstract
Provided is a liquid crystal display device (100) wherein a plurality of pixels include m kinds (m is an even number not less than 4) of pixels (R, G, B, Y) which display colors different by kind. The plurality of pixels are arrayed so that the same sequence composed of n kinds (n is a divisor of m while being an even number not more than m) of pixels out of the m kinds of pixels may be repeatedly placed side by side along the row direction. Each of pixel rows formed by the plurality of pixels includes a plurality of pixel groups to each of which n pixels arranged in series along the row direction belong, wherein gray scale voltages of opposite polarities are supplied, via corresponding signal lines (13), to pixel electrodes (11) of any two mutually adjacent pixels within each of the plurality of pixel groups. Within any two pixel groups adjacent to each other along the row direction out of the plurality of pixel groups, gray scale voltages of opposite polarities are supplied, via corresponding signal lines, to pixel electrodes of pixels that display the same color. A plurality of signal lines include at least one signal-line pair (13p) consisting of two mutually adjacent signal lines that are adjacent to each other and to which gray scale voltages of the same polarity are supplied. A source-drain capacitance in a pixel located between the signal lines of the signal-line pair is smaller than source-drain capacitances in the other pixels. This configuration makes it possible to improve display quality of a liquid crystal display device wherein an even number of pixels define each one picture element.
Description
technical field [0001] The present invention relates to a liquid crystal display device, and more particularly to a liquid crystal display device that performs color display using four or more pixels that display mutually different colors. Background technique [0002] Currently, liquid crystal display devices are used in various applications. In a general liquid crystal display device, one picture element is constituted by three pixels displaying three primary colors of light, red, green, and blue, thereby enabling color display. [0003] However, conventional liquid crystal display devices have a problem that the range of displayable colors (referred to as "color reproduction range") is narrow. Therefore, a method of increasing the number of primary colors used for display in order to expand the color reproduction range of a liquid crystal display device has been proposed. [0004] For example, in Patent Document 1, it is disclosed as Figure 22 A liquid crystal display ...
