Abstract

A method of manufacturing an OLED display deposits an OLED material onto an electrode surface of a substrate through a mask while moving a linear source having nozzles in a first direction. The mask has holes in a surface facing the linear source. Each hole has a first opening and a larger second opening located between the first opening and the linear source. θT<90−θM and SX>D1×tan θM are satisfied. D1 is a distance from the first opening to the electrode surface. θM is the largest incident angle in the first direction of the OLED material. SX is a distance in the first direction from an edge of the first opening to an adjacent sub-pixel electrode. θT is a taper angle defined by a line connecting the edge of the first opening and the edge of the second opening and the first direction.
