ORGANIC LIGHT EMITTING DISPLAY DEVICES AND METHODS OF MANUFACTURING ORGANIC LIGHT EMITTING DISPLAY DEVICES

摘要

An inter-layer bridging connection is provided in an organic light emitting display and a method of manufacturing the same is provided. The organic light emitting display device is subdivided into a major interior, first region I, an auxiliary power coupling region II and a peripheral power line region III where the second region (II) extends at least partially around the first region, and the third region (III) extends at least partially around the second region. Additionally, the display device includes a substrate, a first electrode, a second electrode, an interposed light emitting structure, a power line, a conductive pattern and an auxiliary electrode. The first electrode and the light emitting structure are both disposed in the first region. The power line is disposed in the third region. The second electrode is at least partially transparent and is disposed in the first region and extends into the second region (II). The conductive pattern electrically connects the second electrode with the power line. The auxiliary electrode has reduced resistivity per unit area and directly contacts the second electrode. The auxiliary electrode is disposed in the second region.
