DISPLAY DEVICE FABRICATION METHOD, DISPLAY DEVICE, DISPLAY MODULE, AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/153150
Kind Code:
A1
Abstract:
Provided is a high-definition or high-resolution display device. The display device is fabricated by: forming a first pixel electrode and a second pixel electrode; forming a first layer on the first pixel electrode and the second pixel electrode; forming a first sacrificial layer on the first layer; processing the first layer and the first sacrificial layer to expose at least a portion of the second pixel electrode; forming a second layer on the first pixel electrode and the second pixel electrode; forming a second sacrificial layer on the second layer; processing the second layer and the second sacrificial layer to expose at least a portion of the first sacrificial layer; removing the first sacrificial layer and the second sacrificial layer; forming a third layer on the first pixel electrode and the second pixel electrode; forming a counter electrode on the third layer; and processing the third layer and the counter electrode to remove at least a portion of each of the third layer and the counter electrode included in an area between the first pixel electrode and the second pixel electrode in a top view.
