  • Liquid crystal display
    Patent number: 9291861
    Abstract: According to exemplary embodiments of the invention, a liquid crystal display is provided which includes a plurality of spacers having different heights or a different distance or different pressure tolerance from a corresponding display panel and disposed in at least two pixel areas displaying different colors. As compared with conventional techniques (e.g., disposing the spacers only in one pixel area), the disposition density of the spacer per pixel area is lowered, such that it is possible to prevent the pressure tolerance of the spacer from intensively acting only on a specific pixel. The pressure tolerance of the spacer is uniformly maintained for every pixel, so that insufficiency of the amount of dropping liquid crystal is avoided. As a result, it is possible to prevent the light leakage caused by the insufficient liquid crystal.
