Title:
DISPLAY DEVICE, DISPLAY MODULE, ELECTRONIC APPARATUS, AND METHOD FOR MANUFACTURING DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/052894
Kind Code:
A1
Abstract:
The present invention provides a highly reliable display device. The display device comprises a first conductive layer, a second conductive layer, a third conductive layer, a fourth conductive layer, an insulation layer, a functional layer, and a light-emitting layer. The second conductive layer is provided on the first conductive layer, and the third conductive layer is provided on the second conductive layer. In a cross-sectional view, a side surface of the second conductive layer is positioned further inward than side surfaces of the first and third conductive layers. The insulation layer is provided so as to cover at least a portion of the side surface of the second conductive layer. The fourth conductive layer is provided so as to cover the first to third conductive layers and the insulation layer and electrically connect with the first to third conductive layers. The functional layer is provided so as to have a region that contacts the fourth conductive layer, and the light-emitting layer is provided on the functional layer. The reflectance of visible light of at least one of the first to third conductive layers is higher than the reflectance of visible light of the fourth conductive layer.
