Abstract
A light emitting device includes a metal reflective layer including a phase modulation surface on which oblong phase modulation elements are formed; a first electrode provided on the metal reflective layer; an organic emission layer that is provided on the first electrode and that emits light; and a second electrode provided on the organic emission layer, wherein the oblong phase modulation elements are arranged to form a geometric phase lens.
Claims24
A light emitting device comprising:
- a metal reflective layer comprising a phase modulation surface on which oblong phase modulation elements are formed;
- a first electrode provided on the metal reflective layer;
- an organic emission layer provided on the first electrode, the organic emission layer emitting light;
- and
- a second electrode provided on the organic emission layer,
- wherein the oblong phase modulation elements are arranged to form a geometric phase lens.
A display apparatus comprising:
- a plurality of pixels comprising a first pixel emitting light of a first color and a second pixel emitting light of a second color;
- a metal reflective layer comprising a phase modulation surface on which oblong phase modulation elements are formed;
- a first electrode provided on the metal reflective layer;
- an organic emission layer provided on the first electrode, the organic emission layer emitting white light;
- and a second electrode provided on the organic emission layer,
- wherein the oblong phase modulation elements are arranged to form a geometric phase lens.
A metal reflective layer comprising:
- a surface;
- a plurality of protrusions protruding from the surface that resonate a first range of wavelengths of incident light;
- and
- a plurality recesses recessed from the surface that absorb a second range of wavelengths of the incident light, the second range being different from the first range.
