US Patent 11768401 Display apparatus

A display apparatus includes a liquid crystal panel, a substrate, and a plurality of light emitting diodes (LEDs) provided on one side of the substrate and configured to emit light towards the liquid crystal panel. Each of the plurality of LEDs includes a first reflection layer, a second reflection layer, and a light emitting layer provided between the first reflection layer and the second reflection layer. The second reflection layer is provided between the substrate and the light emitting layer. A first reflectivity of the first reflection layer for a first light entering at a first incident angle is different from a second reflectivity of the second reflection layer for the first light entering at the first incident angle.
