Original Abstract Submitted
An organic light emitting device, a preparation method therefor, and a display apparatus are provided. The organic light emitting device includes an anode, a cathode, and a light emitting layer and an electron transport layer arranged between the anode and the cathode. The electron transport layer is arranged between the light emitting layer and the cathode. The electron transport layer includes a first host material and a second host material. A mixing ratio of the first host material to the second host material of one side of the electron transport layer close to the light emitting layer is different from a mixing ratio of the first host material to the second host material of one side of the electron transport layer away from the light emitting layer.
