ABSTRACT:
The present invention provides a color filter comprising a transmission area and reflection area in which at least one color pixel of red, green and blue pixels is formed of the same material, wherein a transparent area having no color layer is formed in a part of the reflection area, at least one sub-area is formed in the transparent area, and the size of the sub-area is 20 μm or more and 2,000 μm or less. The present invention also provides a liquid crystal display for both transmission display and reflection display with a cheap manufacturing cost, wherein the difference of chromaticity between the transmission display and reflection display is small, and the surface of the transmission area and reflection area have small step heights.
