摘要： 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.
