Abstract

The invention provides a display panel manufacturing method, which comprises the steps of: step S1, attaching a layer of isolating film to the periphery of an operable region of one of a color opticalfilter substrate and an array substrate; step S2, coating a polyimide layer on the surface of the color optical filter substrate and prebaking the surface; S3, peeling off the isolating film; step S4, and performing main baking on the color optical filter substrate, and then performing a liquid crystal injection process. The display panel manufacturing method improves the edge flatness of the polyimide film, shrinks a patterned extension area of the polyimide film, further shrinks an extension region of a frame glue, optimizes the existing frame design, and increases the display scale.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a method for manufacturing a display panel and the display panel. Background technique [0002] In the manufacturing process of TFT-LCD, an alignment film needs to be provided on the array substrate and the color filter substrate of the TFT-LCD, and the alignment film is processed to form grooves along a certain direction so that the liquid crystals are arranged along the direction of the grooves. Alignment film materials have good chemical corrosion resistance, electrical insulation and other properties. [0003] One of the development trends of thin film transistor liquid crystal display is narrow frame display, which reduces non-display area to increase display ratio. In the existing alignment film (polyimide material) coating process, there are uneven edges of polyimide. The actual polyimide patterning needs to be expanded by 1000~4000um (different polyimide materi...
