Abstract: A display substrate is disclosed. In one aspect, the display substrate includes a base substrate having a first refractive index and receiving external light and an insulating layer disposed below the base substrate and having a second refractive index different from the first refractive index. The display substrate also includes a pixel electrode disposed below the first insulating layer and a first compensation layer forming an interface with the insulating layer and having a third refractive index greater than the first refractive index and less than the second refractive index. The first compensation layer is disposed between the first insulating layer and the base substrate.

Abstract: A display apparatus includes a first pixel, a second pixel, a light sensor, and a light shield. The first pixel has a first light-emitting device which includes a first emission layer that emits light in a first wavelength band in a first direction. The second pixel has a second light-emitting device which includes a second emission layer to emit light in a second wavelength band in a second direction different from the first direction. The second emission layer is below the first emission layer of the first light-emitting device. The light sensor senses light in the second wavelength band emitted from the second pixel and reflected by an object. The light shield is arranged along a light path incident to the light sensor.
