A color filter of the present invention includes a large number of colored layers of a plurality of colors regularly arranged together. The color filter is such that&#x2212;0.05&#x2266;+0.05 and&#x2212;0.05&#x2266;0.05or&#x2212;0.10&#x2266;and&#x2212;0.10&#x2266;is satisfied, where (x, y) is the chromaticity in the CIE 1931 chromaticity diagram when the filter alone is irradiated with light to produce a white display, and (x, y) is the chromaticity in the CIE 1931 chromaticity diagram when the filter is irradiated with the same light while being interposed between a pair of polarization plates arranged in a crossed Nicols state each having a degree of polarization of 99.98% or more.

Color filter and liquid crystal display device using the same

A method for producing a color filter includes forming a resinous black matrix on a substrate, and bonding a color film to the substrate and the resinous black matrix. The edge of the matrix is made thinner than an adjoining portion of the matrix to reduce or eliminate foaming and discoloration.

Color filter having colored film and black matrix, display device using the same and method for manufacturing them

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.

Color filter and optical display device

A liquid crystal display apparatus including: a first substrate a plurality of pixel electrodes each provided adjacent to a corresponding one of the intersections of the plurality of signal lines and the plurality of scan lines; a second substrate having a first colored region including a plurality of colors, the first colored region corresponding to the plurality of pixel electrodes; and a liquid crystal layer being interposed between the first substrate and the second substrate. The apparatus further includes a second colored region provided in at least a portion of a periphery of the first colored region, the second colored region including the plurality of colors, wherein at least one of the plurality of signal lines is bent within a region overlapping the second colored region; the second colored region at least includes a plurality of first color layer segments which are colored in a first color, and a plurality of second color layer segments which are colored in a second color; and the plurality of first color layer segments are arranged so that a portion of the at least one signal line which overlaps the plurality of first color layer segments has a length greater than a length of a portion of the at least one signal line which overlaps the plurality of color layer segments other than the plurality of first color layer segments in the second colored region.
