Abstract： |
The invention relates to the cathode structure of an organic electroluminescent device which comprises a base plate, an anode, a cathode and an organic function layer between the anode and the cathode, the cathode comprises a composite electrode shaped by an alternating and multiple-layered structure of a first metal material and an organic material or a second metal material. The technic proposal of the invention solves the problems existing in conventional single-layered cathode structure of pinhole defects and uneven stress when being kinked and prolongs the service life of device and improves flexibility of soft OLED devices. |
