Patent ID: 8624226

Claim:
An organic light emitting device (OLED), comprising: a first substrate; and a second substrate, opposing the first substrate and comprising a plurality of sub-pixels, each of the plurality of sub-pixel comprising a light emitting region and a non light-emitting region; wherein the first substrate comprises a plurality of transistors electrically connected to each other and corresponding to the plurality of sub-pixels of the second substrate, respectively; and for each said sub-pixel, a first connecting electrode electrically connected to the respective one of the plurality of transistors; and wherein the second substrate further comprises, for each said sub-pixel, a light-emitting layer which is formed in the light emitting region and a second connecting electrode which is formed in the non light-emitting region and which is electrically connected to the respective first connecting electrode, the second connecting electrode enclosing an organic layer, the organic layer in the non light-emitting region and the light-emitting layer in the light emitting region are made of the same material and have substantially the same thickness, wherein the light-emitting region of each said sub-pixel of the second substrate comprises: a first electrode formed on the second substrate; the light-emitting layer formed on the first electrode; and a second electrode formed on the light-emitting layer.
