Abstract: A color filter substrate is disclosed, including a substrate, a black matrix disposed on the substrate and multiple color resist blocks separated by the black matrix and disposed on the substrate. Each color resist block is filled with a color resist material, the color resist material includes pigment molecules, including at least one photosensitive substituent. A liquid crystal display device having the same is also disclosed. Utilizing an UV irradiation step in the CF process, the pigment molecules are aligned directionally, which can increase the transmittance of the color filter substrate, the utilization rate of the backlight, and decrease the power consumption. Under the same display brightness, the thickness of the color filter substrate can be decreased; the pigment molecules aligned directionally can make an emitting light to be along a same direction to reduce the light interference between adjacent sub-pixels having different colors to greatly decrease the color shift.

Abstract: The present invention provides a color filter substrate and a display device. The color filter substrate of the present invention includes a backing plate, a black matrix arranged on the backing plate, and a plurality of color resist blocks arranged on the backing plate and spaced from each other by the black matrix. The color resist blocks include a multiple-pore support layer and a color resist material distributed in the multiple-pore support layer. The color resist material includes pigment molecules. The multiple-pore support layer includes a plurality of pores formed therein such that the pores have a size that is greater than a size of the pigment molecules so as to provide effective dispersion and support of pigment molecules, allowing for reducing the amount of non-pigment constituents, such as a dispersion agent and resin, of the color resist material and increasing the content of pigment constituent to thereby improve the performance of light filtration for each unit film thickness of the color resist blocks and allow for thinning of the color filter substrate and an increased density of pixels. The display device of the present invention includes the above-described color filter substrate and shows various advantages, including wide gamut, reduced thickness, and increased brightness.
