Abstract:
The light emitting screen of the present invention includes: a blue light emitting layer emitting blue light by being excited with first excitation light; a green light emitting layer which is disposed on the blue light emitting layer and emits green light by being excited with second excitation light; a red light emitting layer which is disposed on the green light emitting layer and emits red light by being excited with third excitation light; a first selective reflection layer which is disposed between the blue light emitting layer and the green light emitting layer; and a second selective reflection layer which is disposed between the green light emitting layer and the red light emitting layer, wherein the blue light emitting layer, the green light emitting layer, and the red light emitting layer contain quantum rods or quantum dots.
