| titleOfInvention | Blue organic electroluminescent device and method of manufacturing the same |
| abstract | The present invention provides a substrate (1); an anode layer (2) provided on the substrate; a light-emitting layer (5) provided on the anode layer and formed from a blue organic fluorescent material and a hole-type organic host material; A blue organic electroluminescent device, wherein the mass of the blue organic fluorescent material is 8.0% to 25.0% of the mass of the hole-type organic host material; and a cathode layer (8) provided on the light emitting layer. I will provide a. The present invention employs a blue organic fluorescent material whose excited state energy is smaller than that of a hole-type organic host material as a light emitting material. The blue organic fluorescent material has high luminous efficiency and color purity, good thermal stability, excellent electron transport ability, high doping concentration in the light emitting layer, and functions as a host material and a blue light material. Which is advantageous for the balance of the distribution of holes and electrons in the light emitting section, the recombination of holes and electrons can be limited to a narrow region of the light emitting layer, and the distribution of carriers in the light emitting layer can be reduced. Can be balanced. |
