Liquid crystal display panel, display device and method for manufacturing liquid crystal display panel

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.
