Problems solved by technology

However, this method needs to rub the alignment layer multiple times in one pixel, and the manufacturing process is complicated. In addition, it is difficult to manufacture a rubbing roller that rubs multiple times in the same pixel area, which makes the process difficult and difficult to realize.

Abstract

The invention relates to the field of the liquid crystal display technology and discloses a liquid crystal display panel, a display device and a method for manufacturing the liquid crystal display panel. The method for manufacturing the liquid crystal display panel comprises the steps that a first orientation layer is formed on a first substrate, wherein the surface of the first substrate is covered with the first orientation layer, and orientation is conducted on the first orientation layer in the first direction; a second orientation layer is formed on the first orientation layer, wherein orientation is conducted on the second orientation layer in the second direction, the second orientation layer is an elastic siloxane side chain liquid crystal body with a set screw pitch and is provided with at least one orientation unit which corresponds to each line pixel area and penetrates through the line pixel area, and each orientation unit is narrower than the corresponding line pixel area; a second substrate and the first substrate are combined in a vacuum mode. By the adoption of the method for manufacturing the liquid crystal display panel, it is not needed to conduct friction multiple times in each pixel area, multi-domain display can be achieved simply by manufacturing two orientation layers with different orientation directions, and the manufacturing technology is simplified greatly.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal panel, a display device and a method for manufacturing the liquid crystal panel. Background technique [0002] Among flat panel display devices, Thin Film Transistor Liquid Crystal Display (TFT-LCD) has the characteristics of small size, low power consumption, relatively low manufacturing cost and no radiation, and occupies a dominant position in the current flat panel display market. status. Common liquid crystal displays can be used as mobile phone display screens, NoteBook display screens, GPS display screens, LCD TV display screens, etc. With the advancement of science and technology, the traditional monodomain liquid crystal display has been unable to meet people's requirements for liquid crystal display due to its shortcomings such as low contrast, asymmetric viewing angle, and color shift when viewed from different angles. Multi-domain dis...
