Patent ID: 10345660

Abstract:
Disclosed is a manufacturing method of a photo spacer structure of an array substrate, including: forming first pad carriers and second pad carriers having height difference; depositing black photosensitive resin material to cover the first pad carriers and the second pad carriers; implementing exposure to the black photosensitive resin material through a mask, having light transmitting areas and light shielding areas, and light transmission adjusting parts are arranged corresponding to the second pad carriers, and implementing development to form main photo spacers on the first pad carriers, sub photo spacers on the second pad carriers and grooves or trenches in areas around the sub photo spacer with the light transmission adjusting parts; implementing a high-temperature baking and leveling treatment to the black photosensitive resin material to level and fill at least a portion of the resin material of the sub photo spacers to the grooves or the trenches.
