Abstract

An embodiment of the present invention discloses a method for manufacturing a deposition mask, which relates to a method for manufacturing a deposition mask by processing a substrate using a laser to form pattern slits of a deposition mask. The laser cross-section of the substrate is processed with pattern slits.

Description

technical field [0001] Embodiments of the present invention relate to a method of manufacturing a deposition mask. Background technique [0002] Generally, as an active light-emitting display element, an organic light-emitting display device, which is one of flat-panel displays, not only has the advantages of wide viewing angle and excellent contrast ratio, but also has the advantages of being able to be driven by low voltage, being lightweight and flat, 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 display in color. Its development has been extensively carried out recently. ...
