Abstract

Provided is a method of producing a substrate for a light-emitting device whereby a partition consisting of a first partition member and a second partition member can be formed in a small number of steps. The method of producing a substrate for a light-emitting device comprises: a step for forming a first thin film for forming the first partition member on a support substrate; a step for forming a second thin film for forming the second partition member, comprising a photosensitive resin, on the first thin film; a step for removing the remaining areas of the second thin film by photolithography, except the area that overlaps with the area where the first partition member is formed, as viewed from one of the thickness directions of the support substrate; a step for removing the remaining areas of the first thin film by etching, except for the area covered by the second thin film, to form the first partition member; and a step for removing the surface part of the second thin film by etching, to form the second partition member.

Description

technical field [0001] The present invention relates to a method of manufacturing a substrate for a light-emitting device and a method of manufacturing a light-emitting device. Background technique [0002] There are various types of light emitting devices with different light sources. As one of various light-emitting devices, there is a light-emitting device using an organic electroluminescence element (hereinafter sometimes referred to as an organic EL element). A light emitting device using an organic EL element as a light source is used, for example, in a display device. The display device uses an organic EL element as a light source for a pixel, and is currently being gradually put into practical use. This display device includes a plurality of organic EL elements functioning as pixels. A plurality of organic EL elements are arranged in a row on the substrate. Usually, partition walls for partitioning organic EL elements are arranged on a substrate in advance, and o...
