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.


An assembly structure is provided. A first material layer is disposed on a substrate. A hydrophobic layer is chemically attached to the first material layer. A patterned second material layer is disposed on the substrate, without the hydrophobic or slightly chemically attached with hydrophobic molecules and surrounded by the first material layer. A close-loop sealant wall is directly disposed on the patterned second material layer. A cover layer is directly disposed on the close-loop sealant wall to entirely cover the close-loop sealant wall.

A projection display apparatus includes a light source (112) configured to emit a first light, a reflective light modulator (104) configured to modulate the first light to form a second light conveying a rendered image, a polarizer (108) and a light guide plate (106). The light guide plate can include a plurality of optical elements (146) embedded in the thickness of the light guide plate or provided on an outer surface of the light guide plate. An illuminating light entering the light guide plate can be redirected toward the light modulator by reflection at the grooves or optical elements. Moreover, an image light from the light modulator can travel through the light guide plate to the polarizer.
