Title:
METHOD FOR PRODUCING DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/123383
Kind Code:
A1
Abstract:
Provided is a novel method for producing a display device. A positive electrode is formed on an insulation layer, an EL layer is formed on the positive electrode, and a negative electrode is formed on the EL layer. Without providing a partition wall, a plurality of light-emitting elements are formed by selectively removing part of each of the positive electrode, the EL layer, and the negative electrode. A translucent electrically conductive layer is formed so as to cover the plurality of light-emitting elements. The negative electrode of each of the plurality of light-emitting elements is electrically connected to the electrically conductive layer.
