Color filter for liquid crystal displays

Abstract

A reflection-type color filter (30) is disclosed, in which light coming into one surface of a color filter layer (36) is reflected by a reflective layer (40) and allowed to pass through the color filter layer (36) twice. Colored patterns of the color filter layer (36) include resin such as polyimide and dye for dyeing the resin. The thickness of the colored patterns is 0.7 μm or less. In order to enhance light resistance, it is effective to increase the content of dye with respect to resin. The value of 0.7 μm is established in consideration of enhancement of optical characteristic and light resistance of the color filter used in the reflection type liquid crystal display device. In order to enhance light resistance, more preferably, a metal complex is added to the resin.
