Embodiment Construction

[0028] Korean Patent Application No. 10-2009-0037107, filed on Apr. 28, 2009, with the Korean Intellectual Property Office, entitled "Organic Light Emitting Display Device," is hereby incorporated by reference in its entirety.

[0029] Hereinafter, example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0030] In the drawings, the dimensions of layers and regions may be exaggerated for clarity. It will also be understood that when a layer or element is referred to as being "on" another layer or substrate, it can be directly on the other layer or substrate, or intervening layers may also be present. Further, it will be unders...

Abstract

An organic light emitting display apparatus including a plurality of pixels, wherein each pixel includes a first electrode, a second electrode facing the first electrode, and an intermediate layer disposed between the first and second electrodes and including a plurality of layers including a light emitting layer, at least two pixels adjacent in a first direction form a pixel group, and at least one of the layers of the intermediate layer of the at least two adjacent pixels of the pixel group is integrated, and a distance between pixels in the pixel group is smaller than a distance between adjacent pixel groups.

Description

technical field [0001] Various embodiments of the present invention relate to an organic light emitting display device. Background technique [0002] Organic light-emitting display devices may have a wide viewing angle, excellent contrast ratio, and fast response speed, and thus are attracting attention as next-generation display devices. [0003] Generally, an organic light emitting display device may have a stacked structure, for example, a light emitting layer is disposed between an anode and a cathode in the stacked structure. The organic light-emitting display device can realize colored light through the combination of holes from the anode and electrons from the cathode in the emission layer and the combination emits light. However, it is difficult to obtain high-efficiency light emission by such a stack structure, and thus, in addition to the light emitting layer, intermediate layers such as an electron injection layer, an electron transport layer, a hole transport la...
