Problems solved by technology

Therefore, when such a color filter substrate is applied to a liquid crystal display device, the swelling of the colored layer changes the orientation of the liquid crystal molecules, which may lead to a decrease in display quality such as light leakage, a decrease in contrast, and a decrease in color reproducibility.

Embodiment approach 2

[0085] Figure 5 It is a schematic cross-sectional view showing the structure of the color filter substrate of the second embodiment.

[0086] Such as Figure 5 As shown, the structure of the color filter substrate 200 of Embodiment 2 is based on the sum of the thickness of the light-shielding layer 23 and the thickness of the red colored layer 22R or the green colored layer 22G disposed on the light-shielding layer 23, and the thickness of the red colored layer 22G disposed on the light-transmitting region. The thickness of the red coloring layer 22R or the green coloring layer 22G of 222 is formed so that the thickness is equal, and other things are the same as that of Embodiment 1.

[0087] In the color filter substrate 200, a light-shielding layer 23 with a film thickness of 1 μm is disposed on a transparent substrate 21, and a red coloring layer 22R or a green coloring layer is disposed from a light-transmitting region 222 where no light-shielding layer 23 is disposed to...

Abstract

Disclosed is a color filter substrate which enables to suppress disorder in liquid crystal alignment near a light-shielded region, while attaining sufficient light-shielding performance in the light-shielded region. Specifically disclosed is a color filter substrate comprising, on a substrate, a light-blocking layer and a color layer composed of a photosensitive material or the like. The color layer is arranged from a light-transmitting region where the light-blocking layer is not arranged to a light-shielded region where the light-blocking layer is arranged. The thickness of the color layer in the light-shielded region is smaller than the thickness thereof in the light-transmitting region.

Description

technical field [0001] The present invention relates to a color filter substrate, a liquid crystal display panel, a liquid crystal display device, and a method for manufacturing the color filter substrate. More specifically, it relates to a color filter substrate suitable for a liquid crystal display device in a vertical alignment mode, a liquid crystal display panel and a liquid crystal display device having the color filter substrate, and a method for manufacturing the color filter substrate. Background technique [0002] Liquid crystal display devices are thin and low-power display devices, so they are widely used as displays in office automation (OA) equipment such as personal computers, portable information terminal equipment such as electronic notebooks and mobile phones, and integrated video tape recorders (VTR). etc. products. Although the characteristics required for liquid crystal display devices are various, higher-quality display performance is always pursued. T...
