ABSTRACT:
A reflection type color liquid crystal display in which a reflection film is formed on a transparent substrate, and has first transmissive holes for light transmission in a predetermined pattern. A step difference forming layer is installed between the reflection film and the substrate, and has second transmissive holes formed opposite to the first transmissive holes. A color filter layer has unit filter layers formed in a predetermined pattern. The unit filter layers each have a transmissive area with which the first and second transmissive holes are filled and a reflective area which extends from the transmissive area to the reflection film. A transparent front plate is connected to sides of the substrate in so as to form a predetermined interval in between them. A liquid crystal display portion is formed between the color filter layer and a bottom surface of the transparent front plate.
