Abstract
A display panel includes a transmission area, a boundary area adjacent to the transmission area, a display area adjacent to the boundary area, an overcoat layer in the boundary area, a light emitting element in the display area, a first refractive layer on the light emitting element and including the same material as the overcoat layer, and a second refractive layer on the first refractive layer and having a refractive index less than a refractive index of the first refractive layer.
Claims19
A display device comprising:
- a display area including a light emitting element comprising a first electrode, an emission layer, and a second electrode facing the first electrode with the emission layer therebetween;
- a light transmission area corresponding to a functional module providing a function to the display device;
- a boundary area between the light transmission area and the display area;
- a first refractive layer having a first refractive index, the first refractive layer comprising:
- a refractive pattern which overlaps the emission layer of the light emitting element, in the display area, and
- an overcoat layer in the boundary area;
- and
- a second refractive layer on the first refractive layer and having a second refractive index less than the first refractive index of the first refractive layer.

A method of providing a display device, the method comprising:
- providing a light emitting element in a display area of the display device, a functional module in a light transmission area of the display device, and a boundary area between the display area and the light transmission area, the light emitting element comprising a first electrode, an emission layer, and a second electrode facing the first electrode with the emission layer therebetween;
- providing an organic layer having a first refractive index, in the display area and the boundary area;
- providing a first refractive layer having the first refractive index, by patterning the organic layer, the first refractive layer comprising a refractive pattern which is in the display area and overlaps the emission layer of the light emitting element, and an overcoat layer in the boundary area;
- and
- providing a second refractive layer on the first refractive layer, the second refractive layer having a second refractive index less than the first refractive index of the first refractive layer.
