Patent ID: 8193017

Claim:
A method of manufacturing an organic light emitting display device, the method comprising: defining a plurality of pixels on a substrate, each pixel having a first region configured to emit light and a second region configured to transmit external light; forming a plurality of pixel circuit units, such that each of the plurality of pixel circuit units is arranged in the first region of each of the plurality of pixels and includes at least one thin film transistor; forming a plurality of first electrodes, such that each of the plurality of first electrodes is arranged in the first region of each of the plurality of pixels and is electrically connected to a respective pixel circuit unit, the first electrodes being patterned to have an island shape that is separate in each of the plurality of pixels; forming a first organic layer patterned to cover the plurality of first electrodes; forming a second organic layer on the first organic layer, such that the second organic layer includes an emission layer and is patterned to correspond to each of the plurality of first electrodes; forming a third organic layer on the second organic layer, such that the third organic layer is patterned to be in the first region and outside a central portion of the second region; and depositing metal on the third organic layer to form a second electrode on the third organic layer, such that the second electrode includes a first portion only on the third organic layer.
