MASK FOR THIN FILM DEPOSITION AND MANUFACTURING METHOD OF OLED USING THE SAME

摘要

PURPOSE: A mask for depositing a thin film and a method for manufacturing an OLED using the same are provided to prevent the masking failure of a thin film deposition process by reducing the deformation of a rib which is adjacent to the outermost slit of a fine mask. CONSTITUTION: A slit(13) is installed to penetrate through a base unit(11). The pre-set length of the slit expanded to a first direction. An outermost slit(14) is located in a second direction. The second direction is angled to the first direction. A rib(15) is arranged to be adjacent to the outermost slit. A rib support unit(17) is installed between the outermost slit and the rib. The rib support unit is integrated into the base unit.
