Kind Code:
A1
Abstract:
Provided is a display device. The display device comprises: a first base part having a first light-emitting region and a non-light-emitting region defined thereon; a first light-emitting element positioned on the first base part and overlapping the first light-emitting region; a thin film encapsulation layer positioned on the first light-emitting element; a second base part positioned on the thin film encapsulation layer; a first color filter positioned on one surface of the second base part and overlapping the first light-emitting region, wherein the one surface of the second base part faces the first base part; a first wavelength conversion pattern positioned on the first color filter and overlapping the first light-emitting region; and a first optical pattern positioned between the first color filter and the first wavelength conversion pattern and overlapping the first light-emitting region. The refractive index of the first optical pattern is smaller than the refractive index of the first wavelength conversion pattern, and one surface of the first optical pattern includes a curved surface which is concave toward the second base part, wherein the one surface of the first optical pattern faces the first wavelength conversion pattern.
