Apparatus for photo-alignment process, method of fabricating a liquid crystal display substrate, and method of fabricating an apparatus for photo-alignment process

A method of fabricating a liquid crystal display substrate, comprising:

• irradiating an infrared light on a photo-alignment material layer to cure the photo-alignment material layer;
• reflecting the infrared light to generate a reflected infrared light;
• converting the reflected infrared light to an ultraviolet light;
• converting the ultraviolet light to a polarized ultraviolet light;
• and
• irradiating the polarized ultraviolet light on the photo-alignment material layer on a substrate to align the photo-alignment material layer;
• wherein irradiating the infrared light and irradiating the polarized ultraviolet light are performed substantially simultaneously.

A method of fabricating an apparatus for a photo-alignment process, comprising:

• forming a reflector configured to reflect an infrared light;
• forming an up-conversion layer configured to convert the infrared light to an ultraviolet light;
• forming a polarizer configured to converting the ultraviolet light to a polarized ultraviolet light;
• and
• optically coupling the reflector, the up-conversion layer, and the polarizer together so that:
• the reflector is configured to reflect the infrared light and provide a reflected infrared light to the up-conversion layer;
• the up-conversion layer is configured to convert the reflected infrared light to the ultraviolet light, and provide the ultraviolet light to the polarizer;
• and
• the polarizer is configured to convert the ultraviolet light to the polarized ultraviolet light for the photo-alignment process.
