Color filter comprising unit patterns with varied densities and liquid crystal display device using the color filter, and their manufacturing methods |
摘要 |
An object of the invention is to provide a color filter and a liquid crystal display device using the filter, which can obtain well-balanced color purities within a pixel. A color filter for coloring a first light ray L 1 having a unidirectional optical path and a second light ray L 2 having a bidirectional optical path for each pixel. The color filter includes a first area portion 10 t in which the first light ray L 1 is caused to be transmitted and a second area portion 10 r in which the second light ray L 2 is caused to be transmitted, for each pixel. The first area portion 10 t and the second area portion 10 r respectively have structures by which different coloring effects are exerted if light rays having the same optical path and the same property pass through them.
