Abstract
A display device is disclosed. The display device includes a substrate and a plurality of sub pixels on the substrate. Each of the plurality of sub pixels includes an emission area and a non-emission area. A metal layer is disposed on the substrate and is closer to the substrate than other metal layers of the display device. A transmission reduction layer that reduces transmission of external light is between the metal layer and the substrate. The transmission reduction layer has a first surface that is black and less smooth than a second surface of the transmission reduction layer.

A display device comprising:
- a substrate;
- a plurality of sub pixels on the substrate, each of the plurality of sub pixels including an emission area and a non-emission area;
- a metal layer on the substrate, the metal layer closer to the substrate than other metal layers of the display device;
- and
- a transmission reduction layer that reduces transmission of external light, the transmission reduction layer between the metal layer and the substrate and having a first surface that is black and less smooth than a second surface of the transmission reduction layer.
A display device comprising:
- a substrate;
- a plurality of sub pixels on the substrate, each of the plurality of sub pixels including an emission area and a non-emission area;
- a metal layer on the substrate, the metal layer including a plurality of wiring lines and a light shielding layer that are on the substrate;
- and
- a transmission reduction layer that reduces transmission of external light, the transmission reduction layer including a conductive material and has a first surface that is black and less smooth than a second surface of the transmission reduction layer,
- wherein the transmission reduction layer is between the metal layer and the substrate such that the transmission reduction layer overlaps the metal layer.
A display device comprising;
- a substrate;
- a conductive transmission reduction layer that is in contact with an upper surface of the substrate, the conductive transmission reduction layer having a first surface and a second surface that is smoother than the first surface and the first surface is less transmissive of external light than the second surface;
- a metal layer directly on the first surface of the conductive transmission reduction layer such that the conductive transmission reduction layer is between the metal layer and the substrate;
