Abstract

The invention discloses a mask frame assembly, a manufacturing method thereof and a manufacturing method of an organic light-emitting display device. One embodiment of the present invention relates to a mask frame assembly in which a mask is integrally bonded to a frame to selectively pass a deposition substance to be deposited on a substrate, the mask frame assembly is characterized in that it includes a A mask of a deposition area through which a substance passes, a frame having a base portion and a support portion protrudingly formed from the base portion and supporting the mask, and corners of the mask are formed to be bent toward the base portion.

Description

technical field [0001] Embodiments of the present invention relate to a mask frame assembly, a method of manufacturing the same, and a method of manufacturing an organic light emitting display device. Background technique [0002] Generally, as an active light-emitting display element, an organic light-emitting display device, which is one of flat displays, not only has the advantages of wide viewing angle and excellent contrast, but also has the advantages of being able to be driven by low voltage, having a light-weight flat shape, and having a fast response speed. Advantages, thus attracting attention as a next-generation display element. [0003] Such light-emitting elements are divided into inorganic light-emitting elements and organic light-emitting elements according to the material forming the light-emitting layer. Compared with inorganic light-emitting elements, organic light-emitting elements have advantages such as excellent brightness and response speed, and can d...
