Abstract
A display apparatus includes a light source array in which a plurality of light sources emitting light by a local dimming are arranged, a color conversion layer comprising color conversion particles that convert the emitted light into light of a certain color, and configured to emit white light by using the converted light, a display panel configured to generate an image by using the white light, and a selective transmission member arranged between the light source array and the color conversion layer. The selective transmission member is configured to transmit the light to the color conversion layer, and avoid transmitting the light in the color conversion layer to the light source array.
