A light emitting OLED apparatus including a microcavity OLED device having
a broad-band light emitting organic EL element and configured to have
angular-dependent narrow-band light emission, and a patterned
light-integrating element provided over a portion of a light emitting
region of the microcavity device, wherein the light-integrating element
integrates the angular-dependent narrow-band emission from different
angles from the microcavity OLED device to form an integrated light
emission with decreased angular dependence in accordance with the pattern
of the light-integrating element, and the apparatus maintains relatively
angular-dependent emission in light emitting regions of the microcavity
device not provided with the light-integrating element.
