Abstract
An organic light-emitting display device includes: a substrate; a first organic light-emitting layer disposed on the substrate; a pixel defining film disposed on the first organic light-emitting layer and having a first opening, which at least partially exposes the first organic light-emitting layer; and an optical path converter disposed on the pixel defining film to overlap with the first organic light-emitting layer and including a first optical path converting member, which has a first refractive index, and a second optical path converting member, which has a second refractive index that is lower than the first refractive index.
Claims20
An organic light-emitting display device comprising:
- a substrate;
- a pixel defining film disposed on the substrate and including a first opening;
- a first organic light-emitting layer on the pixel defining film, and at least a portion of the first organic light-emitting layer is disposed on the first opening of the pixel defining film;
- and
- an optical path converter on the pixel defining film and overlapping with the first organic light-emitting layer, the optical path converter comprising a first optical path converting member having a first refractive index and a second optical path converting member having a second refractive index that is lower than the first refractive index,
- wherein:
- the first optical path converting member includes a first surface, a second surface opposing the first surface of the first optical path converting member and being shorter than the first surface of the first optical path converting member, a first side surface connecting a first side of the first surface and a first side of the second surface of the first optical path converting member, and a second side surface connecting a second side of the first surface and a second side of the second surface of the first optical path converting member,
- the second optical path converting member surrounds the first and second side surfaces of the first optical path converting member, and
- a length of the second surface of the first optical path converting member is greater than a length of the first opening of the pixel defining film.
