Title:
METHOD FOR MANUFACTURING DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/113179
Kind Code:
A1
Abstract:
The present invention provides a method for manufacturing a display device, said method including: a) a step for preparing a substrate provided with an electrode and another electrode; b) a step for forming a photosensitive resin material layer on the substrate; c) a step for forming a charge transport material layer and a light-emitting material layer on the substrate; and d) a step for patterning the photosensitive resin material layer, the charge transport material layer, and the light-emitting material layer into a photosensitive resin layer, a charge transport layer, and a light-emitting layer, respectively, by leaving, without lifting off, non-lift-off portions of the photosensitive resin material layer, the charge transport material layer, and the light-emitting material layer, which are formed on at least a part of the electrode, and by lifting off lift-off portions of the photosensitive resin material layer, the charge transport material layer, and the light-emitting material layer, which are formed on at least a part of the other electrode.
