Document Type and Number:
WIPO Patent Application WO/2023/033572
Kind Code:
A1
Abstract:
A method for manufacturing a display device according to an embodiment comprises the steps of: self-aligning a light-emitting element in an opening of a planarization layer, the opening overlapping a first assembly line and a second assembly line; successively forming a conductive layer and an organic layer on the planarization layer and the light-emitting element; ashing the organic layer to remove a second portion on a first portion of the organic layer; and etching the conductive layer corresponding to the second portion to form a contact electrode, wherein the contact electrode comes into contact with the flank of a first semiconductor layer at the bottom of the light-emitting element.
