Organic light-emitting device comprising a hole transport layer to which impurities are added at a stepped concentration and a manufacturing method thereof |
| abstract |
An organic light emitting device and a method of manufacturing the same have been proposed which can increase luminous efficiency and color stability and lower driving voltage. According to an aspect of the present invention, an organic light emitting device including a hole transport layer including two or more regions in which a concentration of impurities added to a host forms a stepped concentration gradient is provided.n n n n Organic light emitting device, hole transport layer, impurities, stepped concentration gradient |
