Abstract

The invention discloses a self-aligning liquid crystal display panel and a manufacturing method thereof. In the manufacturing method of the self-aligning liquid crystal display panel, the passivation layer of a TFT substrate is provided as an organic insulating film and organic substances on the surface of the organic insulating film are destroyed by a special treatment method so as to generate -OH and -COOH by decomposition, which facilitates the formation of hydrogen bonds between auxiliary alignment agent and the organic insulating film and increases the anchoring ability of the auxiliary alignment agent on the organic insulating film and solves the problems of the alignment force difference and the bright and dark line displaying defects caused by the surface difference between a pixel electrode and the passivation layer, and achieve even alignment. In addition, the display panel and the manufacturing method thereof further have the advantages that alignment film materials are saved, the related processes of alignment films are eliminated, and further the production cost of the liquid crystal display panels is reduced. The self-aligning liquid crystal display panels are obtained by the above method, achieve the even alignment and have a better displaying quality and do not need arranging the alignment films, so the production cost is lower.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a self-alignment liquid crystal display panel and a manufacturing method thereof. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module (Backlight Module). The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates. There are many vertical and horizontal small wires between the two glass substrates. ...
