Abstract: Provided is a display device. The display device includes a first base portion, a second base portion facing the first base portion, a light emitting layer disposed on one surface of the first base portion and emitting first light, a first wavelength conversion pattern disposed on the light emitting layer and converting the first light into second light having a different wavelength from the first light, a first color filter overlapping the first wavelength conversion pattern on one surface of the second base portion and spaced apart from the first wavelength conversion pattern, and an air layer interposed between the first wavelength conversion pattern and the first color filter.

Abstract: A display device includes a first base portion in which a first emission area and a non-emission area are defined, a first light emitting element on the first base portion and overlapping the first emission area, a thin film encapsulation layer on the first light emitting element, a second base portion on the thin film encapsulation layer, a first color filter on the second base portion and overlapping the first emission area, a first wavelength conversion pattern on the first color filter and overlapping the first emission area, and a first optical pattern between the first color filter and the first wavelength conversion pattern and overlapping the first emission area. A refractive index of the first optical pattern is smaller than that of the first wavelength conversion pattern, and one surface of the first optical pattern facing the first wavelength conversion pattern is concave toward the second base portion.

Abstract: A display device includes a first substrate including a first emission area, a second emission area, and a third emission area, each of which is to emit a first light; a second substrate having a first surface facing the first substrate and a second surface opposite to the first surface; a first color filter, a second color filter and a third color filter, and a first wavelength conversion pattern, a second wavelength conversion pattern and a light-transmitting pattern on the first surface of the second substrate. A thickness of the first color filter is greater than a thickness of the second color filter and the thickness of the second color filter is greater than a thickness of the third color filter.
