Abstract: A display device includes a first display substrate including a first base layer including a display area and a non-display area adjacent to the display area, and a second display substrate including a second base layer including pixel areas overlapping the display area in a plan view and a peripheral area surrounding the pixel areas. The first display substrate further includes light emitting elements respectively overlapping the pixel areas in a plan view, an encapsulation layer including a first inorganic layer covering the light emitting elements, an organic layer disposed on the first inorganic layer, and a second inorganic layer disposed on the organic layer, a bank disposed on the encapsulation layer and including openings respectively overlapping the pixel areas in a plan view, and light control patterns respectively disposed in the openings. The second inorganic layer has a first refractive index in a range of about 1.3 and to about 1.46.

Abstract: A display device includes a plurality of light emitting elements which provide source light, a plurality of light control parts which respectively correspond to the plurality of light emitting elements and have a refractive index, each of the plurality of light control parts receiving the source light and outputting a light having a color, and an encapsulation layer which is between the plurality of light emitting elements and the plurality of light control parts. The encapsulation layer includes in order from the plurality of light emitting elements to the plurality of light control parts, a first inorganic film and a low-refractive index organic film which contacts the first inorganic film and has a refractive index lower than the refractive index of the plurality of light control parts.
