Abstract
A method of fabricating an LCoS display with a color pixel array comprises a step of disposing reflective layers between various color filter layers. The reflective layers are used as etching stop layers between color filter layers so that etching processes are capable of defining patterns of the color filter layers in different sub-pixels for forming the color pixel array.
