Abstract

Provided is a method for manufacturing an organic electroluminescent display apparatus that includes a substrate and a plurality of pixels each including two or more types of sub-pixels, in which the pixels are arranged in a display area of the substrate, and, among the sub-pixels, one type of sub-pixels are specified sub-pixels provided at certain intervals. The specified sub-pixels are formed by selectively forming the (2n - 1)th specified sub-pixels (wherein n represents an integer of 1 or more) numbered from a side end of the display area using a mask having openings at positions corresponding to the (2n - 1)th specified sub-pixels numbered from the side end, and selectively forming the (2n)th specified sub-pixels numbered from the side end using a mask having openings at positions corresponding to the (2n)th specified sub-pixels numbered from the side end.

Description

technical field [0001] The present invention relates to a method for manufacturing an organic electroluminescence (EL) display device. Background technique [0002] An organic electroluminescence (EL) display device is a display device (display) including an organic electroluminescence (EL) element as a self-luminescence element. Therefore, not only a backlight is not required unlike the case of a liquid crystal display, but also a light weight and a small thickness can be achieved. Therefore, organic electroluminescence display devices have attracted attention as next-generation displays having good response speed, viewing angle, and color reproducibility. [0003] Although organic electroluminescent display devices have such excellent properties, the reason why they are not widely sold is that it is difficult to handle organic compound layers (light-emitting layers) having light-emitting properties. In general, in order to manufacture a full-color organic electroluminesc...
