A method for manufacturing a color filter substrate, a color filter substrate, and a liquid crystal display panel

Abstract

The invention discloses a colored-film substrate, a manufacturing method thereof and a liquid crystal display panel and relates to the technical field of liquid crystal display. The colored-film substrate, the manufacturing method thereof and the liquid crystal display panel can be used for solving the problem that the colored-film substrate is low in rate of manufactured finished product and high in cost due to the influence caused by structures of columnar spacers. The manufacturing method of the colored-film substrate, disclosed by the invention, comprises the steps: providing a substrate; forming a black matrix layer on the substrate, and forming a plurality of first preserved holes in one side, far away from the substrate, of the black matrix layer; forming a colored light filtering layer on the substrate; forming protective layers on the black matrix layer and the colored light filtering layer; forming a plurality of second preserved holes in the protective layers, wherein the second preserved holes and the first preserved holes are corresponding in location; forming oriented films on the protective layers, and carrying out frictional orientation; arranging the columnar spacers in the first and second preserved holes of the same locations.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a method for manufacturing a color filter substrate, a color filter substrate and a liquid crystal display panel. Background technique [0002] The color filter substrate is an important part of the liquid crystal display. In the TFT-LCD manufacturing process, the color filter plays an important role in producing colors. Such as figure 1 As shown, the current structure of the color filter substrate includes a glass substrate (glass substrate) 1, an ITO metal layer 2, a black matrix layer 3, a color filter layer (RGB layer) 4, a protective layer 5, and multiple layers regularly arranged on the protective layer 5. A columnar spacer 6. Among them, the columnar spacer 6 can play a role in supporting the thickness of the box when the color filter substrate and the array substrate are boxed together; the protective layer 5 is on the black matrix layer 3 and the color f...
