ABSTRACT:
The thickness of a retardation layer made of a liquid crystalline polymer used in improving visibility in a liquid crystalline display or the like is changed every color pattern of a color filter layer laminated with the retardation layer without adding a special process therefor to realize retardation suitable for each color pattern as the problem of the invention. This problem is solved in the invention by making the total thickness of the layers4and5constant in a structure having black matrix3, color filter layer4and retardation control layer5laminated on substrate2, and changing the thickness of the color filter layer4depending on each pattern, such that each region of the retardation control layer5has predetermined thickness.
