Example Embodiment

[0036] Example 1

[0037] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. The following examples are intended to illustrate the present invention, but not to limit the scope of the present invention.

[0038] like figure 2 As shown, this embodiment takes the TN (Twisted Nematic) mode as an example, the color filter substrate includes: a substrate 1; a color pixel area, which includes a plurality of pixel units, and the pixel units at least include red sub-pixel units 31. The blue sub-pixel unit 33 and the green sub-pixel unit 32; the sub-pixel units of each color in the pixel unit are arranged at intervals on one side of the substrate 1; the black matrix 2 is arranged between the sub-pixel units of each color.

[0039] The material of the substrate 1 may be transparent materials such as glass, quartz, resin, etc., which are not limited herein. In addition, the arrangeme...

[0048] Embodiment 2

[0049] like Image 6 As shown, an embodiment of the present invention provides a method for fabricating the above-mentioned color filter substrate, which includes:

[0050] Step S10, using a patterning process to form a color pixel area on the substrate, which includes a plurality of pixel units, the pixel units at least include red sub-pixel units, blue sub-pixel units and green sub-pixel units; The sub-pixel units are arranged on one side of the substrate at intervals.

[0051] In this step, the sub-pixel units including the red sub-pixel unit 31 , the green sub-pixel unit 32 , and the blue sub-pixel unit 33 are formed on the substrate 1 by coating color photoresist, exposing, and developing. Since the sub-pixel units of each color are fabricated on one side of the substrate 1, the flatness of the side surface is flatter than that of the sub-pixel units of each color disposed on the black matrix 2, and the "bull's horn" phenomenon existing in the prio...

Abstract

The invention relates to the field of display technologies, in particular to a display deice, a color film substrate and a manufacturing method of the color film substrate. The color film substrate comprises a substrate, a color pixel region and black matrixes, wherein the color pixel region comprises a plurality of pixel units; every pixel unit at least comprises a red sub-pixel, a blue sub-pixel unit and a green sub-pixel unit; the various color sub-pixel units in every pixel unit are arranged on one side of the substrate at intervals; and the back matrixes are arranged among the various color sub-pixel units. According to the display deice, the color film substrate and the manufacturing method of the color film substrate, the color pixel region is firstly formed, and then an inkjet process is used to form the black matrixes, so that the angle step of the pixel units is reduced to the largest extent, the flatness of the surfaces of the pixel units is increased and the incidence rate of faulted production lines is effectively reduced; besides, the process of manufacturing the black matrixes through an inkjet mode is adopted, so that, on the one hand, the input costs of preliminary stage production lines are greatly reduced, and on the other hand, the material utilization amount for manufacturing the back matrixes can be reduced and the material utilization rate is improved, and therefore, the production costs are reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device, a color filter substrate and a manufacturing method thereof. Background technique [0002] In recent years, with the development of science and technology, liquid crystal display technology has also been continuously improved. TFT-LCD (Thin Film Transistor-Liquid Crystal Display, Thin Film Field Effect Transistor-Liquid Crystal Display) occupies an important position in the display field due to its advantages of good image display quality, low energy consumption, and environmental protection. At present, TFT-LCD is mainly formed by boxing an array substrate and a color filter substrate, and the cavity after the boxing is filled with liquid crystals. The existing color filter substrate is based on the color filter substrate of the three primary colors of red, green and blue. The liquid crystal panel controls the arrangement state of the liquid crystal molecules...
