Abstract
An active matrix organic electroluminescent device includes a thin-film transistor, an organic electroluminescent device, and a spacer layer deposited between the thin-film transistor and the organic electroluminescent device, wherein the spacer layer is made of adhesive for a dual curing system selected from the group consisting of ultraviolet curing-thermal curing, ultraviolet curing-microwave curing, ultraviolet curing-anaerobic curing, and ultraviolet curing-electron beam curing system. The present invention solves the poor adhesiveness between the thin-film transistor and the organic electroluminescent device, and improves the moisture and oxygen proof ability. The preparation method is simple, effective, and able to lower the cost and difficulty, and greatly improve the yield rate of the device.
