Abstract
According to one embodiment, a display device includes a first lower electrode and a second lower electrode, a power supply line, a first organic layer including a light emitting layer and covering the first lower electrode, a second organic layer including a light emitting layer and covering the second lower electrode, a first upper electrode being in contact with the power supply line and covering the first organic layer, a second upper electrode being in contact with the power supply line and covering the second organic layer, and a first inorganic insulating film covering the first upper electrode and the second upper electrode and exposing the power supply line.
Claims8
A display device comprising:
- a substrate;
- a first insulating layer arranged on the substrate;
- a first lower electrode and a second lower electrode arranged on the first insulating layer;
- a second insulating layer arranged on the first insulating layer, and including a first opening which overlaps the first lower electrode and a second opening which overlaps the second lower electrode;
- a power supply line arranged on the second insulating layer;
- a first organic layer including a light emitting layer, arranged at the first opening, and covering the first lower electrode;
- a second organic layer including a light emitting layer, arranged at the second opening, and covering the second lower electrode;
