ABSTRACT:
The invention enables color characteristics to always be enhanced in both reflection mode display and transmission mode display in the transreflective type liquid crystal device. The present invention provides a liquid crystal device including a color filter formed on one substrate of a pair of substrates with interposition of a liquid crystal. The color filter includes a dividing material14to divide the surface of the substrate into plural regions, a reflection layer formed in each region, a color pixel and a protective layer formed on the reflection layer. The thickness of the reflection layer is significantly different within the divided region, and a high transmission region having a transmittance of 50% or less is formed in the reflection layer formed to be thinner than the reference thickness. When the color pixel is formed with a thick film corresponding to the high transmission region, a bright display becomes possible in the reflection mode display, and a transreflective type liquid crystal device is obtained with enhanced color characteristics in both transmission mode display and reflection mode display.
