種を用いた。 The samples include a conventional color filter that prioritizes saturation, a color filter that prioritizes light fastness, a color filter that balances saturation and light fastness, and a color filter of the present invention.

好な原因としては、高耐光性の着色層によつて、
可視光のうち所望の波長域以外の光の多くが吸収
されるため、高彩度着色層に入射する光量が実質
的に減少するためである。 On the other hand, in the color filter of the present invention and the color filter in which light resistance was prioritized, there was no deterioration in red (R), green (G), and blue (B) even after 50 hours or more. The reason why the color filter of the present invention has good light resistance is due to the highly light-fast colored layer.
This is because most of the visible light outside the desired wavelength range is absorbed, so the amount of light that enters the high chroma colored layer is substantially reduced.
次に、カラーフイルターの色純度を1931年の

れる。 Next, we compared the color purity of the color filters on the 1931 C, I, E chromaticity diagram, and found that the color purity of the color filter of the present invention was higher than that of the conventional color filter that prioritized saturation, which has high color purity. It was still high enough, with almost no difference. The color purity of the color filter of the present invention is high despite the provision of a highly light-fast colored layer with low color purity.
Even if a highly light-fast colored layer is provided, the transmittance at the maximum transmission wavelength of each color in the spectral transmission spectrum will only slightly decrease, and this decrease in transmittance will not have much of an effect on color purity. it is conceivable that.

As described above, the color liquid crystal display element of the present invention, which is equipped with a color filter having a two-layer structure of a highly light-fast colored layer and a highly chromatic colored layer, can provide clear images and has excellent reliability. It has the effect that can be obtained.
