    摘要： An organic light emitting display (OLED) and method of fabricating the same are provided having a reduced number of photolithography and etching steps. The method includes a source electrode and a drain electrode being formed over a substrate, and at least one insulating layer being formed over the source electrode and drain electrode. After the insulation layer is formed, a reflecting layer pattern is formed. A via contact hole is formed through the insulating layer using the reflecting layer pattern as an etching mask. Multiple insulating layers may be formed and have a via contact hole etched therethrough in one etching step using the reflecting layer pattern as a mask. Alternatively, each insulating layer may have a via contact hole separately etched therethrough, with the last layer being etched using the reflective layer pattern as a mask. Consequently, the number of photolithography and etching steps is reduced thereby leading to higher manufacturing yield and lower manufacturing cost.

    摘要： An organic light-emitting display device and a method of fabricating the device are disclosed. The organic light-emitting display device includes a thin-film transistor positioned on a substrate that has a semiconductor layer, a gate electrode, and source and drain electrodes. A first electrode is positioned, which is connected to either the source electrode or drain electrode. A reflective layer, which is spaced apart from the source electrode or drain electrode, is positioned below the first electrode. An organic functional layer having at least an emission layer is positioned on the first electrode. A second electrode is positioned on the organic functional layer. The first electrode, the reflective layer, the organic functional layer, and the second electrode constitute an organic light-emitting diode.

    摘要： An OLED and a method of fabricating the same are provided, in which, when a reflective layer pattern is formed, a thin layer for a pixel electrode is opened at an edge of an emission region to form the pixel electrode without additional photolithography and etching processes by forming an undercut under the edge of the reflective layer pattern, i.e., under the edge of the emission region by over-etching, thereby simplifying the process and increasing the yield.

    摘要： An organic light emitting diode (OLED) display. The OLED display includes: a lower electrode formed on a layer on an insulating substrate having a thin film transistor. The lower electrode is electrically connected to the thin film transistor. An auxiliary electrode is formed on the same layer as the lower electrode, and a pixel defining layer is formed on edges of the lower electrode, thereby defining an opening which exposes a portion of the lower electrode. An organic layer is formed on the portion of the lower electrode exposed by the opening, and an upper electrode is formed on an entire surface of the insulating substrate and electrically connected to the auxiliary electrode. An edge of the auxiliary electrode may have a taper angle of at least 90°.
