Abstract
A wiring is inhibited from being visible. Alternatively, a display device or a touch panel with high viewability is provided. A semiconductor device includes a transistor and a wiring electrically connected to the transistor that are over a light-transmitting substrate. Furthermore, a layer including an oxide semiconductor is provided closer to a substrate side than the wiring is so as to overlap with the wiring and serve as an anti-reflection layer that suppress light reflection at the wiring.
Claims12
A semiconductor device comprising:
- a transistor over a substrate;
- a wiring over the substrate;
- and
- a first layer over the substrate,
- wherein the substrate transmits visible light,
- wherein the transistor comprises a gate electrode, a semiconductor layer, a first electrode, and a second electrode,
- wherein the wiring is electrically connected to the gate electrode, the first electrode, or the second electrode,
- wherein the first layer is closer to the substrate than the wiring is,
- wherein the first layer and the wiring overlap with each other in a region, and
- wherein the first layer comprises an oxide semiconductor.
