Abstract
A reflective display apparatus is provided, which includes a liquid-crystal-on-silicon (LCOS) display module and a compensation layer. The LCOS display module has a liquid crystal layer. The liquid crystal layer includes liquid crystal cells, each having a beta angle ranging from about 9 degrees to about 11 degrees and a twist angle ranging from about 84 degrees to about 88 degrees relative to the beta angle. The compensation layer is disposed on the LCOS display module for compensating retardation of the liquid crystal layer.
