A top panel and a bottom panel each with an alignment film are provided; a mask plate for shielding the top panel and the bottom panel is provided, and a transparent section of the mask plate is disposed; an ultraviolet is emitted along a first incident direction by the mask plate for exposing the alignment film of the top panel and the bottom panel; the transparent section of the mask plate is adjusted, an ultraviolet is emitted along a second incident direction by the mask plate for exposing the alignment film of the top panel and the bottom panel. The manufacture of the alignment film in the whole liquid crystal display device can be accomplished by a mask plate undergoing exposure twice, so that the exposure times decrease and the process is simplified."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Mask plate, photo-alignment method and liquid crystal display device","description":"The disclosure is related to a photo-alignment method, comprising the following steps.
