Abstract
The present disclosure relates to an organic electroluminescent device, in which co-host materials with a specific P:N ratio are used, and the energy level and mobility of the materials of the functional layers are adjusted to be within specific ranges, so that good device performances could be produced under a plurality of P:N ratios, thereby providing more possibilities for the selection of devices.
