Abstract

A liquid crystal display device having two-pixel multi-domain pixels, in which columnar spacers are arranged at optimum positions. A plurality of image lines each have a part A of an acute angle among two crossing angles intersecting each scanning line, which is a positive angle in the clockwise direction from each scanning line, and a part B, which is a negative angle clockwise from each scanning line , part A and part B are arranged alternately with the scan line sandwiched between them. When one of the odd-numbered scanning line and the even-numbered scanning line is set as the scanning line A, and the other scanning line is the scanning line B, the main columnar spacer is arranged on the scanning line A and on the adjacent scanning line. At the intersection position where the image lines between the sub-pixels of the three colors and the sub-pixels of the first color intersect, the sub-columnar spacer is arranged on the scanning line B and adjacent to the sub-pixels of the third color and the sub-pixels of the first color. The intersection location where the image lines intersect.

Description

technical field [0001] The present invention relates to a liquid crystal display device, and more particularly to a method of arranging columnar spacers for maintaining a constant distance between a first substrate and a second substrate. Background technique [0002] Currently, most commonly used liquid crystal display devices are composed of a pair of substrates (for example, glass substrates) and a liquid crystal composition sealed in the gap between them. Specifically, for example, in the case of an IPS liquid crystal display device, thin film transistors, pixel electrodes, signal lines, and gate electrodes are formed on a substrate (hereinafter referred to as a TFT substrate). , a counter electrode, and the like, and a light-shielding film, a color filter, and the like are formed on another substrate (hereinafter, referred to as a CF substrate). Furthermore, the TFT substrate and the CF substrate are arranged facing each other with a constant gap maintained by a spacer...
