Abstract
A display panel and a display device are provided. The display panel includes an organic electroluminescence device and a color conversion layer disposed on the organic electroluminescence device. The color conversion layer includes a quantum dot material and an organic electroluminescence material. The organic electroluminescent material is added to the color conversion layer. By mixing the organic electroluminescent material and the quantum dot material, the organic electroluminescent material forms excitons under excitation of blue light, and then singlet state excitons are transferred to quantum dots by fluorescence resonance energy, thereby improving an efficiency of the color conversion layer.
