Claim:
1. A method of manufacturing an organic electroluminescent device, comprising: forming a first electrode on a predetermined region of an insulating base; conducting a surface treatment to an upper surface of the first electrode and an upper surface of the insulating base which is not covered by the first electrode, so that the upper surface of the first electrode is lyophilic, and the upper surface of the insulating base which is not covered by the first electrode is lyophobic; forming an electroluminescent layer on the first electrode; and forming a second electrode on the electroluminescent device, wherein prior to forming the first electrode on the insulating base, further comprising: forming a thin film transistor on a base substrate; forming the insulating base on the base substrate and the thin film transistor, the insulating base being formed with a via hole therein at a position corresponding to a drain electrode of the thin film transistor, wherein forming the first electrode on the insulating base comprises: forming the first electrode on the upper surface of the insulating base and in the via hole, and the first electrode being electrically connected to the drain electrode via the via hole, and wherein one of the first electrodes and the second electrode is an anode of the organic electroluminescent device, and the other one is a cathode of the organic electroluminescent device.
