Problems solved by technology

However, in this alignment method, each exposure process can only form one alignment direction
Therefore, if it is desired to form multi-region alignment, it is necessary to perform multiple exposure processes, which makes the process steps cumbersome.

Embodiment Construction

[0040] Figure 1A It is the process flow of the manufacturing method of the photo-alignment film of an embodiment of the present invention, and Figure 1B for Figure 1A A cross-sectional view of the exposure method of step 40. in addition, figure 2 It is a schematic diagram of an optical alignment film according to an embodiment of the present invention. Please refer to Figure 1A , The manufacturing method of the photo-alignment film of this embodiment includes at least the following steps.

[0041] Firstly, step 10 is performed to provide an alignment liquid, wherein the alignment liquid includes a photopolymerizable alignment material and a photodecomposable alignment material. For example, the ratio of the photopolymerizable alignment material and the photodecomposable alignment material contained in the alignment liquid may be 1:1. In addition, the photodegradable alignment material can decompose under the first energy, while the photopolymerizable alignment material...

Abstract

The invention discloses a production method for orientation solutions and optical orientation films, comprising: first, providing an orientation solution containing an optical polymerization orientation material and an optical photolysis orientation material; coating the orientation solution on the baseboard provided with a plurality of first regions and second regions; then, radiating the linear polarized light via optical components on the orientation solution on the baseboard; the linear polarized light passes through the optical components to radiate part of the first regions to decompose the photolysis orientation material of the orientation solution and the linear polarized light synchronously passes through the optical components to radiate part of the second regions to polymerize the photolysis orientation material of the orientation solution.

Description

technical field [0001] The present invention relates to a method for manufacturing an alignment film and an alignment material, and in particular to a method for manufacturing a photo alignment film (photo alignment film) and an alignment liquid. Background technique [0002] A liquid crystal display panel is mainly composed of an active element array substrate, an opposite substrate and a liquid crystal layer. When an electric field is applied between the opposite substrate and the active element array substrate, the liquid crystal molecules in the liquid crystal layer will be deflected by the electric field, so that the liquid crystal layer has light transmittance corresponding to the electric field. In this way, the liquid crystal display panel can display different grayscale images according to the magnitude of the electric field between the opposite substrate and the active element array substrate. In order for the liquid crystal molecules to meet the requirements of f...
