The invention discloses a blue light organic electroluminescence device and a display device including the same. The blue organic electroluminescence device includes a hole transport layer, an electron blocking layer, a light-emitting layer, a hole blocking layer and an electron transport layer arranged in sequence, and the light-emitting layer at least includes a first host and a second host; Wherein, the first host and the second host are homologues of anthracene or isomers of anthracene. The present invention can at least partially solve the problems of low luminous efficiency, short lifespan and low yield of OLED blue light devices in the prior art. |
