Patent ID: 8004639

Claim:
A liquid crystal display (LCD) panel, comprising: a first substrate including a plurality of pixel units arranged in an array, wherein each of the pixel units has at least one transmittance area, and the first substrate has a plurality of concaves having a size located in the transmittance areas; a second substrate located above the first substrate; a plurality of alignment protrusions disposed on the second substrate and located in the center of each of the transmittance areas, respectively, a height of each of the alignment protrusions being approximately the same, the size of one concave being approximately capable of accommodating one of the alignment protrusions, wherein in the transmittance areas, a group of the alignment protrusions are located in the concaves so as to keep a gap from the first substrate, and another group of the alignment protrusions located outside of the concaves contact with the first substrate directly; and a liquid crystal layer located between the first substrate and the second substrate.
