摘要:
A liquid crystal display device using columnar spacers to eliminate an influence of shades in rubbing an orientation film and to eliminate remaining of display unevenness (black haze) in black display is provided. Columnar spacers are provided above a black matrix of an opposite substrate disposed opposite to a TFT substrate. A position of a top of each columnar spacer in contact with the TFT substrate is shifted from a center of a gate line of the TFT substrate toward a common line parallel to the gate line. Moreover, a structure is adopted, in which the top of the columnar spacer contacting with the TFT substrate is not entirely brought into contact with the TFT substrate, but a gap is provided between a part of the top of the columnar spacer and the TFT substrate by providing an irregular surface on the top of the columnar spacer or the like. This gap can reduce frictional force between the top of the columnar spacer and the TFT substrate to result in restricting an occurrence of the black haze when external force is applied to a screen of the liquid crystal display device.
