Abstract

The application discloses a self-aligned liquid crystal display panel and a processing method thereof. Alignment material is added to liquid crystal molecules. The processing method comprises: a cleaning agent is prepared, the bonding agent is added to the cleaning agent, and the bonding agent comprises a first binding group which can be combined with the alignment material; the substrate is cleaned with the cleaning agent so that the bonding agent adheres to the surface of the substrate, thereby increasing the bonding force between the substrate and the alignment material, thereby improving the alignment stability; the cleaned substrate is dried. The bonding agent attached to the surface of the substrate is combined with the alignment material to increase the bonding force between the substrate and the alignment material, thereby improving the alignment stability.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a method for processing a self-aligned liquid crystal display panel and its substrate. Background technique [0002] Liquid crystal display panels generally need to coat an alignment layer on the color filter substrate and the thin film transistor array substrate to align the liquid crystal molecules, and polyimide (PI) film is usually used as the alignment film. According to different alignment methods, it can be divided into rubbing alignment, electrification alignment and ultraviolet light irradiation alignment. Regardless of the alignment method, the manufacturing process is very complicated, and there will be many defects, such as local non-alignment due to non-sticking of the alignment film, and uneven brightness caused by uneven thickness of the alignment film. Therefore, the display mode without PI alignment film is adopted, that is, adding additives to the li...
