  • Liquid crystal display panel and method for fabricating color filter substrate
    Patent number: 7466384
    Abstract: A liquid crystal display panel comprising a first substrate, a second substrate, and a liquid crystal layer is provided. A plurality of first pixel regions, second pixel regions and third pixel regions are defined on the second substrate. A first alignment protrusion structure is disposed in the first pixel regions, a second alignment protrusion structure is disposed in the second pixel regions, and a third alignment protrusion structure is disposed in the third pixel regions. Wherein, the heights of the first, second and third alignment protrusion structures are different. The liquid crystal layer is disposed between the first substrate and the second substrate.
