摘要

The present invention relates to a mask for forming an OLED pixel, a manufacturing method thereof and a manufacturing method of a frame integrated mask. According to the present invention, the mask for forming an OLED pixel comprises: a mask cell (C) formed with a plurality of mask patterns (P); and a dummy (DM) around the mask cell (C). A plurality of welding parts (WP) are formed at intervals on at least a part of the dummy (DM). Wrinkle prevention patterns (150-170) are formed around an area in which the welding parts (WP) are spaced apart from each other by a predetermined distance. In each of the welding parts (WP), a thickness reinforcement pattern (180) is formed on at least one of the welding part (WP) and the wrinkle prevention patterns (150-170).;COPYRIGHT KIPO 2020
