  • Color filter, color filter forming material and process for producing color filter
    Patent number: 6686105
    Abstract: A color filter having a light-transmissive support and two or more color-developing layers, which develop hues differing from each other, laminated on the support. Each color-developing layer is developed into a predetermined color pattern including pixels. The pixels of the developed color patterns of the layers either overlap in a direction of lamination or do not overlap in the direction of lamination. Also provided are a color filter forming material produced by laminating the two or more photosensitive and heat-sensitive color-developing layers on the light-transmissive support, and a process for producing a color filter by exposing each photosensitive and heat-sensitive color-developing layer of the above color filter forming material to form a predetermined pattern, heating the photosensitive and heat-sensitive color-developing layers, and fixing the developed color patterns.
