Organic light-emitting device having improved light-emitting efficiency and method for fabricating the same
The present invention provides an organic light emitting device in which a layer having a refractive index in the range of 1.3 to 3 is further formed on an upper electrode of at least one region of regions through which rays having red, green, and blue colors are passed and a method of manufacturing the organic light emitting device. An optical length that can cause the microcavity effect according to the type of color of emitted light is controlled by using the layer to manufacture the organic light emitting device having high light emitting efficiency.
