Abstract: A display device includes a display panel, a wavelength control layer disposed on the display panel, a light control member disposed on the wavelength control layer, and a cover layer disposed on the light control member. The light control member includes an inorganic layer disposed on the wavelength control layer and having a first refractive index, a first light control layer disposed on the inorganic layer and having a second refractive index, a second light control layer disposed on the first light control layer and having a third refractive index, and a color filter layer disposed on the second light control layer. The first refractive index is greater than the second refractive index and is less than a refractive index of the wavelength control layer, and the third refractive index is greater than the second refractive index and is less than a refractive index of the color filter layer.

Abstract: A display panel includes a circuit board and an element layer disposed on the circuit board and including a pixel defining layer having a plurality of openings, and a spacer disposed on the pixel defining layer. The plurality of openings include a first opening, a second opening, and a third opening that are adjacent to the spacer. The spacer includes a central portion disposed between the first, second, and third openings and a first extension, a second extension, and a third extension that protrude from the central portion in three directions, respectively. End portions of the first, second, and third extensions are disposed in a region defined by virtual lines connecting a first center of the first opening, a second center of the second opening, and a third center of the third opening.

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.
