ABSTRACT:
An organic electro-luminescence display device includes first pixels formed aver an optically transparent substrate, each of the first pixels including a first organic electro-luminescence element, which includes a first optically transparent and electrically conductive layer, an organic layer including a light-emitting layer, a second optically transparent and electrically conductive layer and a first optically reflective and electrically conductive layer in order, and second pixels formed over the optically transparent substrate, each of the second pixels including a second organic electro-luminescence element which includes a second optically reflective and electrically conductive layer, the first optically transparent and electrically conductive layer, the organic layer including the light-emitting layer and the second optically transparent and electrically conductive layer in order. Accordingly, the first organic electro-luminescence element and the second organic electro-luminescence element commonly share same layers, thus minimizing the thickness of the device.
