Title:
DISPLAY DEVICE, DISPLAY MODULE, AND METHOD FOR PRODUCING DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/118140
Kind Code:
A1
Abstract:
Provided is a high-definition display device. The display device is provided with a plurality of light-emitting elements that emit light of different colors. A microcavity structure (microresonator structure) is realized for the light-emitting elements to intensify light of a specific wavelength. The light-emitting elements emitting light of different colors each include, on a lower electrode, a reflection layer and a conductive layer having a different thickness. The bottom electrode and the conductive layer are electrically connected within a light-emitting element. The light-emitting elements are separately formed so that different colors are intensified due to different optical path lengths.
