Abstract
The invention discloses an organic light emission diode device. The organic light emission diode device comprises a substrate, a conductive anode, a first hole injection auxiliary layer, a second hole injection auxiliary layer, a hole transmission layer, a light emission layer, an electron transmission layer, an electron injection layer and a cathode which are sequentially laminated, the material of the first hole injection auxiliary layer is molybdenum trioxide, vanadium pentoxide, tungsten trioxide or rhenium oxide, and the material of the second hole injection auxiliary layer is 2,3,6,7,10,11- hexcyano-1,4,5,8,9,12-hexaazatriphenylene. The invention also discloses a fabrication method of the organic light emission diode device. According to the fabrication method of the organic light emission diode device provided by the invention, through additional arrangement of dual hole injection auxiliary layers in the conductive anode and the hole transmission layer, hole injection capability is improved, and the organic light emission diode device prepared according to the fabrication method thereof has low driving current and high luminous efficiency.
