ORGANIC LIGHT EMITTING DISPLAY DEVICE AND METHOD FOR MANUFACTURING THE SAME

摘要

An OLED device is disclosed. The OLED device includes: a substrate defined into an active area in which a plurality of pixels are formed in a matrix shape, a GIP (gate-in-panel) area in which drive elements are formed, a ground contact area, and a seal line area; a thin film transistor formed in each pixel region within the active area; an organic light emission diode formed on a protective film and configured to include a first electrode, an organic light emission layer and a second electrode; a bank layer formed to divide the organic light emission diode into pixel units; a signal wiring formed in the ground contact area and the seal line area; and an extended portion formed from the same material as the first electrode of the organic light emission diode and configured to cover the signal wiring, wherein a seal line within in the seal line area is formed on an edge of the signal wiring, which is covered with the extended portion, and an interlayer insulation film adjacent to the edge of the signal wiring. Such an OLED device can prevent a stained fault generation in the seal line region by largely forming a connection electrode, which makes contact with signal wirings formed along edges of an active area, and covering the signal wirings with a metal pattern.
