GRAYSCALE MASK PLATE, COLOR FILM SUBSTRATE, RELATED FABRICATING METHODS, AND DISPLAY DEVICE

摘要

A grayscale mask plate and method of fabricating the same, a color film substrate and method of fabricating the same, and a display device are disclosed. The grayscale mask plate comprises a transparent substrate and a light blocking layer on the transparent substrate. The light blocking layer comprises an exposure region with an optical translucent film which has a light blocking ratio decreasing gradually or stepwise from a center of the optical translucent film to an edge of the optical translucent film. As a result, the intensity of light transmitted through the exposure region is uniform, such that a post spacer fabricated by the grayscale mask plate has a relatively flat top face. Thus, the post spacer exhibits a linear variation in its hardness under the action of an external force.
