Abstract: A display device includes a first display substrate including a light emitting element which emits light of a first color or light of a second color different from the first color, a second display substrate including in order toward the first display substrate, a layer including both a bank layer defining an opening and a wavelength control pattern in the opening, a capping layer covering the wavelength control pattern and the bank layer, and a color absorbing layer which corresponds to the bank layer and blocks the light of the first color and the light of the second color. The capping layer includes a first area corresponding to the color absorbing layer, the bank layer includes a second area corresponding to the color absorbing layer, and the first area of the capping layer is between the color absorbing layer and the second area of the bank layer.

Abstract: A display device includes: a substrate, where a first pixel area, a second pixel area, and a third pixel area which are defined on the substrate; and a plurality of light blocking members disposed on the substrate between the pixel areas. The light blocking members include a plurality of first light blocking members continuously extends along a first direction between the first, second and third pixel areas, and a second light blocking member disposed along a second direction perpendicular to the first direction, the second light blocking member is disposed between neighboring third pixel areas which neighbor each other in the first direction, and a width of the first light blocking member and a width of the second light blocking member are substantially the same as each other.

Abstract: A display device includes: a substrate including an alignment area in a non-display area, and a display area including a plurality of material layers on the substrate; in the alignment area, a plurality of keys including a first alignment key and a second alignment key. Each alignment key includes a light blocking pattern, a layer pattern and a display pattern. The position of the display pattern within the first alignment key is different from the position of the display pattern within the second alignment key, the layer pattern of the alignment key and one material layer among the plurality of material layers are respective portions of a same material layer on the substrate, and the layer pattern of the first alignment key and the layer pattern of the second alignment key are respective portions of different material layers among the plurality of material layers on the substrate.
