Abstract: PROBLEM TO BE SOLVED: To provide a color filter capable of improving the color balance in a white display, and a liquid crystal display device using the same, especially a reflective or a semitransmissive-semireflective liquid crystal display device. SOLUTION: The color filter is characterized by containing red pixels of which the chromaticity coordinate (x, y) in the XYZ colorimetric system chromaticity diagram satisfies inequalities 4816x3-4855x2+1294x+3>Y>4654x3-4579 x2+1162x+9 and 0.350

Abstract: PROBLEM TO BE SOLVED: To provide a color filter in a liquid crystal display element concurrently attaining a transmissive display and a reflective display with little difference of chromaticity between the two and being flat. SOLUTION: The color filter for the liquid crystal display element is characterized by making pixels with at least one color have a transmissive region and a reflective region composed of the same color material, forming a region without any color material in the reflective region and having a compensation layer to compensate difference of chromaticity between the transmissive region and the reflective region caused by respective light sources used in both regions in the region without any color material.

Abstract: PROBLEM TO BE SOLVED: To provide a color filter exhibiting characteristics similar to a color filter with a pinhole provided on a reflective region at a similar manufacturing cost to, and more easily flattened than, any conventional one. SOLUTION: In the color filter having at least a reflective region and a transmissive region, each of the regions composed of the same material, in a pixel with one color and having a thin film thickness region provided on a part of a coloring layer of the reflective region, if the film thickness of the thin film thickness region is represented by d1 and the film thickness of the normal film thickness region is represented by d0 , the color filter for a semitransmissive liquid crystal display element is characterized by having d1 larger than 0 μm and d0 -d1 smaller than 2 μm.

Abstract: PROBLEM TO BE SOLVED: To obtain a red paste for a color filter of a reflection-type liquid crystal display device, capable of providing a red filter which can realize both of high transmittance and color purity by effectively using the ambient light. SOLUTION: Color filter for a reflection-type liquid crystal display device consists of red pixels containing a coloring agent, having a threshold wavelength for transmittance at >=550 nm and =20% average transmittance in the range from 430 nm to 470 nm when the average transmittance from 480 nm to 530 nm is 10%.
