Patent ID: 7355339

Claim:
An organic electroluminescent display providing enhanced monochromatic and highly directed light comprising: an organic electroluminescent device, having a microcavity structure, for emitting light resonating in the microcavity structure; a light-gathering structure, overlying the organic electroluminescent device, for gathering the light emitted from the organic electroluminescent device; and a light-shielding layer comprising a light-absorbing member for preventing external light transmitted from the outside from being reflected, overlying the light-gathering structure, having an opening through which a portion of the light gathered by the light-gathering structure passes, wherein the light-gathering structure includes a lens having a focus, and the opening of the light-shielding layer is disposed in the vicinity of the focus of the lens, wherein the lens and the light-shielding layer having the opening cooperate to converge resonating light emitted from the microcavity structure at the opening of the light-shielding layer.
