Problems solved by technology

However, due to the reduction in current times resistance (I*R) that occurs between the low potential pixel power supply and the point where it is applied to the emissive layer through the cathode's conductive material, brightness may not be uniform within the pixel cell

Abstract

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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2013-0079447 filed with the Korean Intellectual Property Office (KIPO) on Jul. 8, 2013, the entire disclosure of which is incorporated herein by reference. technical field [0003] The present disclosure relates to an organic light emitting display device and a method of manufacturing such an organic light emitting display device. More particularly, the exemplary embodiments relate to an organic light emitting display device having improved uniformity of light emission and a method of manufacturing the same. Background technique [0004] Specifically, among flat or otherwise thin panel display devices, an organic light emitting display (OLEDD) displays images by using an organic light emitting diode as a light emitting device. Organic light-emitting display devices have become noteworthy next-generation display devices because of their excellent br...
