摘要： An organic light emitting device includes an anode, a hole function layer disposed on the anode, a light emitting layer disposed on the anode, and a cathode disposed on the light emitting layer. The hole function layer includes a main layer that does not include an n-type dopant and a p-type dopant. The hole function layer also includes a n-doped layer disposed between the main layer and the light emitting layer, and the n-doped layer includes an n-type dopant.

摘要： A display device includes a red pixel, a green pixel, and a blue pixel comprising a plurality of transistors and an organic light emitting element. The organic light emitting element has a value of a temperature sensitive factor (TSF) in a range of about 0.25×10−1 Cd·m2/V to about 0.51×10−1 Cd·m2/V as shown in a following equation:
