Color filter and liquid crystal display device using the same
Abstract:
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 xWH−0.05≦xB≦xWH+0.05 and yWH−0.05≦yB≦yWH+0.05 or xWH−0.10≦xB≦xWH and yWH−0.10≦yB≦yWH is satisfied, where (xWH, yWH) is the chromaticity in the CIE 1931 chromaticity diagram when the filter alone is irradiated with light to produce a white display, and (xB, yB) 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.
Abstract(Chinese):

本发明的滤色器包括大量有规则地排列在一起的多种颜色的着色层。 滤色片使得<？in-line-formula description =“In-line Formulas”end =“lead”？> x -0.05 <= x B ＆lt; =＆lt; WH＆lt; /＆gt; +0.05和＆lt; WH＆lt; -0.05＆lt;＆lt;＆lt;＆lt;＆lt;＆lt; ？in-line-formula description =“In-line Formulas”end =“tail”？>或<？in-line-formula description =“In-line formula”end =“lead”？> x < /SUB>-0.10<=xB<=XWH 和Y -0.10 <= y <= Y <？in-line-formula description =“内联公式”end =“tail”？>被满足，其中（x < SUB> WH ）是当用光照射过滤器以产生白色显示时CIE1931色度图中的色度，并且（xBB，yB） SUB>）是当以相同的光照射滤光器时CIE1931色度图中的色度，同时插入以每个具有99.98％或更大的偏振度的正交尼科尔斯态布置的一对偏光板之间。
