Problems solved by technology

[0002] In recent years, the process requirements of devices in the display field have become higher and higher. For the alignment film layer, most of them are polyimide aligners. The film layer formation process is generally to form the precursor of the aligner on the substrate, and then The precursor undergoes high-temperature curing and cross-linking, and finally forms an alignment object. However, when the precursor is cured at high temperature, some film layers of the display panel will cause cracks due to high temperature, which will affect the stability of the display panel.

Abstract

The embodiment of the invention discloses a manufacturing method of a display panel. The manufacturing method of the display panel comprises the following steps: providing a first substrate; forming a first alignment solution film layer comprising a first alignment object and a first solvent on the first substrate; removing the first solvent in the first alignment solution film layer to form a first alignment layer; and providing a second substrate, and aligning the second substrate with the first substrate, wherein the boiling point temperature of the first solvent is lower than the curing synthesis temperature of the precursor of the first alignment object. According to the embodiment of the invention, the alignment substance is dissolved in the solvent with a lower boiling point to form the solution, the alignment solution film layer is formed on the substrate, the solvent is removed through evaporation, and the alignment substance film layer is formed, so that a high-temperature curing step required by a precursor is avoided, cracks of the film layer of the display panel are reduced, and the stability of the display panel is enhanced.

Description

technical field [0001] The invention relates to the display field, in particular to a method for manufacturing a display panel. Background technique [0002] In recent years, the process requirements of devices in the display field have become higher and higher. For the alignment film layer, most of them are polyimide aligners. The film layer formation process is generally to form the precursor of the aligner on the substrate, and then The precursor is cured and cross-linked at high temperature, and finally forms an alignment object. However, when the precursor is cured at high temperature, some film layers of the display panel will cause cracks due to high temperature, which will affect the stability of the display panel. [0003] Therefore, there is an urgent need for a method for manufacturing a display panel to solve the above technical problems. Contents of the invention [0004] The embodiment of the present invention provides a method for manufacturing a display pa...
