Abstract

This application provides an alignment film transfer printing plate including a substrate, a first dot arranged on the substrate, and a plurality of second dots arranged around the first dot. A height of each of the second dots in a direction perpendicular to a surface of the substrate is less than or equal to a height of the first dot in the direction perpendicular to the surface of the substrate, a blocking portion is formed on an end of the first dot away from the substrate, and an area of an end surface of each of the second dots away from the substrate is less than an area of an end surface of the blocking portion away from the substrate.
