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.
Claims14
An organic light-emitting display device comprising:
- a substrate;
- a pixel defining layer on the substrate and having a plurality of first openings,
- an organic light-emitting layer in the first openings of the pixel defining layer;
- and
- an optical path converter on the pixel defining layer and comprising a first portion having a plurality of second openings overlapping with the plurality of first openings, and a second portion comprising at least a portion located in the second openings,
