Abstract
An organic light emitting diode display is disclosed. The organic light emitting diode display includes: a substrate, an organic light emitting diode positioned on the substrate, a metal layer positioned on the substrate with the organic light emitting diode interposed therebetween, and a resin layer positioned on the metal layer and configured to reinforce a strength of the metal layer.
Claims12
A display device, comprising:
- a substrate;
- a wiring unit positioned on the substrate;
- an organic light emitting diode positioned on the wiring unit and including a first electrode, a second electrode that is farther from the substrate than the first electrode, and an organic emission layer disposed between the first electrode and the second electrode;
- a metal layer positioned on the organic light emitting diode and having a thermal expansion coefficient lower than a thermal expansion coefficient of the substrate;
- and
- an adhesive layer positioned between the organic light emitting diode and the metal layer, the adhesive layer directly contacting the second electrode of the organic light emitting diode,
- wherein the adhesive layer is thicker in a portion that overlaps both the second electrode and the organic emission layer, in a vertical direction, than at a portion that overlaps the second electrode but not the organic emission layer, in the vertical direction, and
- wherein the display device further comprises a resin layer positioned on the metal layer and having a thermal expansion coefficient higher than the thermal expansion coefficient of the substrate and the thermal expansion coefficient of the metal layer.
