Embodiment Construction

[0016] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of various exemplary embodiments. It will be apparent, however, that various exemplary embodiments may be practiced without these specific details or with one or more equivalent arrangements. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring the various exemplary embodiments.

[0017] In the drawings, the size and relative sizes of layers, films, panels, regions, etc., may be exaggerated for clarity and illustration. Additionally, the same reference numerals refer to the same elements.

[0018] When an element or layer is referred to as being "on," "connected to," or "coupled to" another element or layer, it can be directly on, directly connected to, or coupled to the other element or layer to another element or layer, or intervening elements or laye...

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority to and the benefit of Korean Patent Application No. 10-2015-0062022, filed on April 30, 2015, which is hereby incorporated by reference for all purposes as if fully set forth herein. technical field [0003] Exemplary embodiments relate to an organic light emitting display device capable of accurately displaying an image while increasing the brightness of the organic light emitting display device. Background technique [0004] In general, an organic light emitting display device is a display device that displays an image by using light emitted from an emission layer disposed between a pixel electrode and a counter electrode. Organic light emitting display devices typically include pixel electrodes electrically connected to thin film transistors through which electronic signals are applied to control light emission or luminosity in each subpixel. [0005] The organic light emitting displ...
