摘要

Provided are a masking unit (100) and a mask plate assembly provided with the masking unit. The masking unit (100) is used for the evaporation forming of pixels of an organic light-emitting display. The masking unit (100) comprises a coating area (11), which is provided with multiple evaporation openings (110) for the evaporation forming of the pixels. The masking unit further comprises a first auxiliary area (12), wherein the first auxiliary area (12) is provided with at least one first side portion (12a) adjacent to at least one side of the coating area (11); each of the first side portions (12a) comprises at least one row of first openings (120); each of the first openings (120) extends in a direction from the inside to the outside of the first side portion (12a); and the width of each of the first openings (120) gradually decreases in the extending direction thereof. The coating area (11) in the masking unit (100) is connected to a peripheral region thereof by means of the first auxiliary area (12), and on the basis of a gradient pattern of the first openings (120) in the first auxiliary area (12), the probability of breakage at the position of the junction between the coating area (11) of the masking unit (100) and the peripheral region of the coating area can be effectively reduced.
