Abstract

A manufacturing method for a BOA array substrate (40, 50, 60) comprises: manufacturing an array substrate (40, 50, 60), and forming a metal layer (413, 513) in a non-display area (412, 512, 612) of the array substrate (40, 50, 60); coating a display area of the array substrate (40, 50, 60) with a black matrix and performing a patterning process on the black matrix; and forming color photoresists (53, 63) on the array substrate (40, 50, 60). The present invention also provides a BOA array substrate (40, 50, 60). By means of the manufacturing method for the BOA array substrate (40, 50, 60) and the BOA array substrate (40, 50, 60), the manufacturing quality thereof can be improved, and the image display quality of a liquid crystal display panel is improved.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a method for manufacturing a BOA array substrate and the BOA array substrate. Background technique [0002] Color filter array integration technology (BOA, Black Matrix ON Array), can reduce the deviation of the alignment of the two substrates, increase the aperture ratio of the liquid crystal display panel, and reduce the parasitic capacitance of the liquid crystal display panel, and is widely used in the production of liquid crystal display panels middle. [0003] When making a black matrix (Black Matrix) on an array substrate, since the black matrix does not have light transmission, when exposing the black matrix, it is easy to cause alignment deviation between the array substrate and the black matrix, thereby affecting the BOA array substrate. The production quality will further affect the image display quality of the liquid crystal display panel. [0004] Therefore, i...
