Abstract: Provided is an organic light emitting display panel with uniform luminance. A flattening layer including a contact hole is disposed on a substrate on which an auxiliary electrode is disposed. The contact hole in the flattening layer has an undercut pattern at a point contacting the auxiliary electrode. The organic light emitting layer is disconnected by the contact hole, but the common electrode is connected with the auxiliary electrode at an undercut pattern portion with a high step coverage as compared with the organic light emitting layer. Since the auxiliary electrode and the common electrode are connected with each other through the contact hole having the undercut pattern in the flattening layer, it is possible to preserve uniform luminance of the organic light emitting display panel.

Abstract: An organic light emitting diode (OLED) display device is described that includes a shared cathode between OLED pixels as well as auxiliary lines that are formed between rows and/or columns of the OLED pixels. As the cathode is shared between many if not all of the pixels of display device, resistance within the cathode can affect the brightness of those pixels that are further from the cathode's voltage source. The auxiliary lines serve to counteract the voltage drop caused by this resistance. The auxiliary lines are electrically connected to the cathode in close proximity to individual pixels of the display.
Abstract translation: 描述了一种有机发光二极管（OLED）显示装置，其包括OLED像素之间的共享阴极以及形成在OLED像素的行和/或列之间的辅助线。 由于阴极在许多（如果不是全部）显示装置的像素之间共享，则阴极内的电阻可以影响距离阴极的电压源更远的像素的亮度。 辅助线用于抵消由该电阻引起的电压降。 辅助线路电连接到阴极，靠近显示器的各个像素。
