Abstract:
1. A method for fabricating an organic EL device, the method comprising: forming a TFT in the unit of pixel on a substrate; forming a first insulating layer on an entire surface of the substrate including the TFT; forming a via-hole penetrating the first insulating layer; forming an electrode separator on a predetermined portion of the first insulating layer so as to separate anodes from each other in the unit of pixel, wherein the electrode separator is formed in a shape that an upper width is larger than a lower width at a boundary between the pixels; depositing an anode material on an entire surface of the first insulating layer including the via-hole and the electrode separator, such that the anodes are automatically separated from each other by the electrode separator, wherein each of the anodes is formed in the unit of pixel and is connected with the thin film transistor through the via-hole in the unit of pixel; forming a second insulating layer at a portion except for an emission area of the each pixel on the anode and electrode separator, wherein the second insulating layer covers the electrode separator and the anode material on the electrode separator; and sequentially depositing an organic EL layer and a cathode on the anode including the second insulating layer, wherein the anode is below the organic EL layer and the cathode is on the organic EL layer.
