ABSTRACT:
A reflection type color liquid crystal display includes a step difference forming layer installed between a reflection film and a substrate second transmissive holes formed opposite to first transmissive holes, a color filter layer with unit filter layers which are formed in a predetermined pattern and which 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 connected to sides of the substrate to form a predetermined interval between the transparent front plate and a transparent substrate, and a liquid crystal display portion formed between the color filter layer and a bottom surface of the transparent front plate. The step difference forming layers create differences in thickness between the reflective areas and the transmissive areas.
