Embodiment approach 1

[0112] The liquid crystal display device 100A of Embodiment 1 has figure 1 and figure 2 (a) Pixel structure shown. image 3 The display status shown is the same as Figure 9 The display states shown differ in the polarity distribution of the pixels in columns 5-8 and the concomitant bright sub-pixels within the color display pixels formed by the pixels in columns 5-8. configuration in the column direction. By setting the polarity of the display signal voltage provided to the pixels in the 5th to 8th columns by S-C5 to S-C8 to be the same as that provided to the pixels in the 1st to 4th columns by S-C1 to S-C4 shows that the polarity of the signal voltage is reversed, it is possible to obtain image 3 The display status shown.

[0113] when concerned image 3 When the pixels in the first row of the row, the arrangement of the pixels in the two color display pixels adjacent to each other in the row direction is Y(+), R(-), G(+), B(-), Y(-) , R(+), G(-), B(+), according ...

Abstract

A liquid crystal display device (100A) according to the present invention includes a plurality of pixels (10) which are arranged in columns and rows to form a matrix pattern. Each of the plurality of pixels (10) includes first and second subpixels (10a, 10b), which are arranged in a column direction, one of which is a bright subpixel that exhibits a higher luminance than the other at least at a particular grayscale, and the other of which is a dark subpixel. The plurality of pixels define a plurality of color display pixels, each of which includes an even number of pixels including first, second, third and fourth pixels (Y, R, G, B) that are arranged in a row direction. In an arbitrary row of pixels, a row of subpixels including the bright subpixels includes the respective bright subpixels of all of the first, second, third and fourth pixels.

Description

technical field [0001] The present invention relates to a liquid crystal display device, in particular to a liquid crystal display device having a pixel division structure and utilizing four or more pixels displaying mutually different colors to perform color display. Background technique [0002] Since the MVA (Multidomain Vertical Alignment: multi-domain vertical alignment) type liquid crystal display device has wider viewing angle characteristics than the TN type liquid crystal display device, it is widely used in liquid crystal display devices such as TV applications (for example, refer to Patent Document 1 and Patent Document 2). [0003] In the MVA type liquid crystal display device, on the side of the liquid crystal layer of a pair of substrates facing each other across the vertical alignment type liquid crystal layer, a domain restriction structure (also called an orientation restriction structure) is provided to form the alignment direction of the directing dipole. ...
