Title:
DISPLAY DEVICE AND DISPLAY DEVICE SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2019/049360
Kind Code:
A1
Abstract:
This display device according to the present invention is configured by an opposing substrate (100) and an array substrate (200). The opposing substrate (100) is provided with: a transparent substrate (40); a second wiring (2) including a first black color layer and a first conductive layer formed on an observation surface (S) of the transparent substrate (40); a first insulation layer (I) covering the second wiring (2); and a first wiring (1) configured by a second black color layer and a second conductive layer, orthogonal to the second wiring (2), and formed on the first insulation layer (I). The array substrate (200) is provided with: a substrate (45); a third wiring (83) and a fourth wiring (84) configured by a third conductive layer formed on a second surface (N) of the substrate (45); a fifth wiring configured by a fourth conductive layer formed on a second surface of a second substrate and orthogonal to the third wiring and the fourth wiring; a first thin film transistor and a second thin film transistor having a channel layer made of an oxide semiconductor; and a vertical light emitting diode (CHIP) functioning as a display function layer. The first to fourth conductive layers have a structure in which a copper layer or a copper alloy layer is sandwiched by a first conductive metal oxide layer and a second conductive metal oxide layer.
