<p>Disclosed are a mask plate (300), an evaporation device for manufacturing an organic light-emitting display panel and a method therefor. The mask plate (300) comprises a plurality of opening regions (310) distributed in an array, wherein each of the opening regions (310) comprises a first opening region (311) and second opening regions (312) provided at the four corners of the first opening region (311), which are arranged in a matrix, and the second opening regions (312) are in communication with the first opening region (311). By changing the design of the opening regions (310) of the mask plate (300), the area of the invalid film-forming region of the opening regions (310) is reduced, thus improving the opening rate of an organic light-emitting display panel.</p> |
