Organic light emitting device display and method of manufacturing the same
First Claim
1. An organic light emitting device display, comprising:
- a first electrode in red, green, and blue sub-pixels on a substrate;
a hole injection layer above the substrate so as to cover the first electrode;
a hole transport layer above the hole injection layer;
an auxiliary layer between the hole injection layer and the hole transport layer in the red sub-pixel;
a red light emission layer and a green light emission layer above the hole transport layer in the red sub-pixel and the green sub-pixel, the red light emission layer being between the green light emission layer and the hole transport layer; and
a blue light emission layer above the hole transport layer in the blue sub-pixel,the red light emission layer and the green light emission layer being co-extensive and the blue light emission layer not overlapping the red light emission layer or the green light emission layer.
