摘要： A color conversion substrate comprising: a base substrate including a display area, a peripheral area positioned around the display area, and a sealing area positioned around the peripheral area; a color filter layer in the display area under the base substrate; a color conversion layer including a plurality of color conversion parts spaced apart from each other on a bottom surface of the color filter layer; a light blocking member in the peripheral area and the sealing area under the base substrate and including light blocking layers, wherein the light blocking layers overlap each other in a first direction that is a thickness direction of the base substrate and extend in a second direction perpendicular to the first direction; and a column spacer on a bottom surface of the light blocking member and extending in the second direction to be in the peripheral area and the sealing area.

摘要： A display apparatus including a light emitting device layer emitting a first light having a peak wavelength of 500 nm or less, a color control layer disposed on the light emitting device layer, the color control layer including an emitting element converting the first light, a color filter layer disposed on the color control layer, and an absorptive scattering element provided in or on the color control layer. The absorptive scattering element may include a light absorbing portion, in which absorptivity of a green or red light is greater than absorptivity of the first light. Accordingly, reflectance of the display apparatus to an external light may be reduced.
