Abstract
A light-emitting device includes a metal reflection layer having a phase modulation surface, a color conversion layer provided on the phase modulation surface of the metal reflection layer, a first electrode provided on the color conversion layer, a hole injection and transport layer provided on the first electrode, a blue organic light-emitting layer provided on the hole injection and transport layer, an electron injection and transport layer provided on the blue organic light-emitting layer, and a second electrode provided on the electron injection and transport layer. The phase modulation surface of the metal reflection layer generates magnetic resonance with respect to incident light. The color conversion layer includes a photoluminescent material.
