滤色器的评价方法、滤色器以及液晶显示装置
摘要：
本发明提供滤色器的评价方法、滤色器及液晶显示装置。所述滤色器在基板上至少具备3色以上的着色显示像素，所述评价方法的特征在于，对所述着色显示像素分别从任意的角度照射380nm～780nm范围内包括透射光峰区域的波长λ在内的连续的光，并使用分光椭圆偏振仪进行测定，在将测得的相位差值设为Δ(λ)、并将所述着色显示像素在380nm～780nm范围内的所述波长λ下的分光透射率设为T(λ)时，对各着色显示像素由下述式(1)求得值ξ1，通过该值ξ1来判断具备所述滤色器的液晶显示装置的斜方向的可视性。式中、a、b表示所述连续的照射光的波长范围，是满足380≤a、b≤780且a＜b的数值。
摘要（英）：

The invention provides a method for evaluating a color filter, the color filter and a liquid crystal display device. The color filter includes a substrate, and at least three color pixels disposed thereon. The method for evaluating a color filter is characterized in that a continuous light including a wavelength lambda of a transmitting light peak region in a range from 380 nm to 780 nm is applied to each of the colored display pixels from an arbitrary angle so as to measure a phase difference Delta(lambda) by using a spectral elipsometer. The spectral transmittance of the colored display pixel in the range of 380 nm to 780 nm is assumed to be T(lambda). The value Xi1 obtained by the expression (1) given below for each of the colored display pixels is used to judge the oblique-direction visibility of a liquid crystal display device having the color filter. In the formula, a and b are values respectively representing a wavelength range of a continuous wavelength light and satisfying conditions of 380<=a, b<=780 and a
