Problems solved by technology
The surface of the recessed area is not flat, so that after the alignment layer is rubbed, the alignment layer will have uneven rubbing orientation, which will cause light leakage; and the uneven surface of the alignment layer will also make it contact with the alignment layer. The fluidity of the liquid crystal molecules is poor, which will cause problems such as pressing color difference

Embodiment Construction
[0048] The word "embodiment" as used in this specification means serving as an example, instance or illustration. Furthermore, the article "a" as used in this specification and the appended claims may generally be construed to mean "one or more" unless specified otherwise or clear from context to refer to a singular form.
[0049] In the embodiment of the present invention, by first forming the first OC layer in the W sub-pixel area, and ensuring that the R, G, and B color-resist layers are consistent with the thickness of the first OC layer in the W sub-pixel area, in this way, the overall coating After covering the second OC layer, the coverage of the second OC layer is flat. Therefore, the embodiment of the present invention can avoid sags in the W sub-pixel area, thereby effectively avoiding light leakage in RGBW pixels, and effectively improving the problem of color difference when pressed.
[0050] In order to illustrate the technical solutions of the present invention,...

Provided is a method for fabricating a color filter substrate: patterning a first OC layer (200), retaining the first OC layer (200) of a W subpixel region; patterning a black matrix layer (300), retaining the black matrix layer (300) of the black matrix layer region; forming an RGB color filter on the color filter region of a substrate (100), the RGB color filter having the same thickness as the first OC layer (200) of the W subpixel region; applying a second OC layer (500) onto the substrate (100); depositing a transparent metal layer (600) onto the second OC layer (500). The described fabrication method prevents recesses from appearing on the W subpixel region.
Description
【Technical field】 [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a color filter substrate, a color filter substrate, and a liquid crystal display panel. 【Background technique】 [0002] In the prior art, the principle of RGBW liquid crystal screen technology is to add a white (W) sub-pixel to the traditional RGB pixel composed of red (R), green (G) and blue (B), and then Then apply the corresponding sub-pixel imaging technology to better arrange these sub-pixels in the way humans see images. This ensures that display power and brightness sources are not lost when generating images that cannot be seen by the human eye. RGBW sub-pixel imaging technology addresses each sub-pixel individually, and adds a white sub-pixel to the arrangement pattern to form an RGBW pixel design, which is brighter and clearer than the traditional RGB pixel design. rate is higher. Because more backlight can shine through the larger and s...
