Liquid crystal display device having dummy electrodes with interleave ratio same on all sides |
摘要 |
A liquid crystal display device includes a pair of substrates having a plurality of display-use electrodes formed thereon, a seal for connecting the pair of substrates in such a manner that respective electrode forming surfaces face each other, a liquid crystal layer formed by sealing a liquid crystal in a space surrounded by the pair of substrates and the seal, and dummy electrodes for achieving a uniform thickness of the liquid crystal layer in the display area. The display-use electrodes and the dummy electrodes are interleaved on four sides of the seal, and an absolute value for variations in interleaved ratio in the four sides, indicative of a ratio of an area occupied by the display-use electrodes and the dummy electrodes on the seal is not more than a predetermined value. As this permits a uniform thickness of the seal on the four sides, a difference in brightness between a central portion and a portion in a vicinity of the seal in the display area can be eliminated, thereby improving a display quality.
