An organic electroluminescent display includes an organic
electroluminescent device, having a microcavity structure, for emitting
light resonating in the microcavity structure; a light-shielding layer
having an opening through which a portion of the light emitted from the
organic electroluminescent device passes; and a light-gathering
structure, disposed between the organic electroluminescent device and the
light-shielding layer, for gathering the light emitted from the organic
electroluminescent device. An apparatus includes a controller for
providing image information; an organic electroluminescent device, having
a microcavity structure, for emitting light resonating in the microcavity
structure, based on the image information provided from the controller; a
light-shielding layer having an opening through which a portion of the
light emitted from the organic electroluminescent device passes; and a
light-gathering structure, disposed between the organic
electroluminescent device and the light-shielding layer, for gathering
the light emitted from the organic electroluminescent device.
