Manufacturing method of alignment film

Abstract

The invention relates to a manufacturing method of an alignment film, comprising the following steps that an alignment material with an ultraviolet ray reaction functional group is formed on a substrate; the alignment material on the substrate is pre-baked; an ultraviolet ray polaroid is provided arranged on the substrate; the pre-baked alignment material is aligned so as to cause irradiate the ultraviolet rays to irradiate on the substrate; the ultraviolet rays penetrates the ultraviolet ray Polaroid polaroid and irradiates to the pre-baked alignment material; and the alignment material which is aligned is baked so as to completely solidify the alignment material. By the manufacturing method disclosed by the invention, uneven alignment and dark-state light leakage can be reduced, a relative good process yield is provided, and an effect of wide viewing angle can be achieved.

AI Technical Summary

Benefits of technology

This patented technology describes an improved way for making alignments between two layers made from different types of polymers without damaging them during production. It involves exposing these aligned films under UV lights before curing it. By doing this, they become stronger over time due to their ability to combine multiple chemicals together into one molecule instead of just mixing each other's components separately. Overall, this new technique allows for easier handling and higher yields while maintaining good quality results.

Problems solved by technology

This patented technical solution involves creating an alignment pattern on one side (the top) of a transparent plate used with LCD displays while another plane called its backplane faces towards them. To ensure proper performance, there needs to be no air bubbles during assembly. Additionally, due to their small sizes, they may also cause issues like electrostatic discharge damage if exposed too much time after manufacturing.
