Title: MASK AND ASSEMBLING METHOD THEREFOR
Abstract:
Provided are a mask (01) and an assembling method therefor, which can prevent a relatively wide middle area from getting into a state of crimping downward when a skeleton structure (10) is fixed on a frame (30), therefore stabilizing a contact state between the skeleton structure (10) and a mask sheet (20). The mask (01) comprises a plurality of strip-shaped skeleton structures (10), the mask sheet (20) which is supported by the skeleton structures (10) and has a mask pattern (201), and the frame (30) having an opening area (30a), wherein each of the skeleton structures (10) comprises a middle portion (101) and extending portions (102) at the two ends; the width of the middle portion (101) is greater than the width of the extending portions (102); the frame (30) is provided with a groove (31) connected to the opening area (30a); and the extending portions (102) at the two ends, and a transition area (101a), close to the extending portion (102), of the middle portion (101), of the skeleton structure (10) are located in the groove (31), and a fixing point (40) where the skeleton structure (10) and the groove (31) are fixed with each other is at least provided in the transition area (101a).
