Abstract

A microcavity color OLED device, includes at least one light-emitting layer arranged so as to produce light; a reflector and a semi-transparent reflector forming a microcavity structure for resonating the light produced in the at least one light emitting layer; and a color filter element disposed over the microcavity structure including a light-scattering material selected so as to reduce the angular dependence of the light that has passed through the color filter element.
