Abstract
A color filter frame, which covers a non-display surface of an optical display section, is provided with frame color filter picture elements using at least two of three colors used for color filter picture elements, which correspond to displaying pixels. An area ratio of the frame color filter picture elements corresponding to different colors is set so as to be different from that of the color filter picture elements, which correspond to the colors used in the frame color filter picture elements. With this arrangement, it is possible to omit the step of manufacturing a black mask so as to reduce the cost; consequently, a color filter for an optical display device can be provided with an excellent appearance on a display.
