Abstract
A display device includes a substrate, a circuit element layer on the substrate, a display element layer on the circuit element layer, a sealing film on the display element layer, an oxide film on the sealing film, a barrier metal layer on the oxide film, and a wiring layer on the barrier metal layer, wherein a surface of the sealing film in contact with the oxide film has concave/convexities, and the barrier metal layer is formed by titanium nitride. A height of the concave/convexities of the surface of the sealing film may be less than 30 nm. A thickness of the oxide film may be 5 nm or less.
Claims15
A display device comprising:
- a substrate having a pixel region and a periphery region arranged in an outer side of the pixel region;
- light-emitting elements in the pixel region;
- a sealing film covering the light-emitting elements, the sealing film including
- a first inorganic insulation layer,
- a first organic insulation layer on the first inorganic insulation layer, and
- a second inorganic insulation layer on the first organic insulation layer;
- a detection electrode overlapping both the pixel region and being in contact with the second inorganic insulation layer;
- a wiring located on the sealing film, electrically connected to the detection electrode, and overlapping both the pixel region and the periphery region;
- and
- a second organic insulation layer located between the substrate and the light-emitting elements, overlapping both the pixel region and the periphery region, and having a first opening in the periphery region,
- wherein
- the wiring overlaps the first opening, and
- the first inorganic insulation layer is in contact with the second inorganic insulation layer in the first opening.
