Claim:
1. A liquid-crystal-on-silicon (LCOS) display apparatus, comprising: a silicon substrate having a plurality of pixels arranged in a matrix, wherein each of the plurality of pixels has a tilting angle ranging from substantially 0 degrees to substantially 90 degrees, and each of the plurality of pixels comprises a pixel electrode; a color filter layer on the plurality of pixel electrodes, wherein the color filter layer has a plurality of color filter units, and each of the plurality of color filter units respectively corresponds to one of the plurality of pixel electrodes; a first alignment layer on the color filter layer; a second alignment layer opposite to the first alignment layer; and a liquid crystal layer between the first alignment layer and the second alignment layer, wherein the liquid crystal layer has a plurality of liquid crystal molecules with negative dielectric anisotropy, and each of the plurality of liquid crystal molecules has a beta angle substantially equal to 15 degrees and a twist angle of substantially equal to 45 degrees.
