Problems solved by technology

In this case, the contact hole formed adjacent to the pixel area may have a height difference, so that the organic transfer layer may be transferred unevenly in the pixel area.
Therefore, pixel defects may easily occur in organic light-emitting display devices

Embodiment Construction

[0032] Various embodiments will be described more fully hereinafter with reference to the accompanying drawings in which certain embodiments are shown. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this description will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, the size and relative sizes of layers and regions may be exaggerated for clarity.

[0033] It will be understood that when an element or layer is referred to as being "on," "connected to" or "coupled to" another element or layer, the element or layer can be directly on, the other element or layer. Directly connected or coupled to such another element or layer, or intervening elements or layers may be present. When an element is referred to as being "directly on," "directly connected to" or "directly co...

Abstract

Provided are an organic light emitting display device and a method of manufacturing the organic light emitting display device. Thin film transistors may be on the substrate. An insulating interlayer having first to third contact holes may be disposed on the substrate. A first electrode electrically connected to the thin film transistor may be located on the insulating interlayer and on sidewalls of the first to third contact holes. A pixel defining layer may be disposed on the insulating interlayer, part of the first electrode, and sidewalls of the first to third contact holes. The light emitting structure may be disposed on the first electrode in the pixel area. A second electrode may be on the light emitting structure. A planarization pattern may be disposed on the pixel defining layer to fill up the first contact hole and the second contact hole. Spacers may be disposed on the pixel defining layer to fill up the third contact holes.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Korean Patent Application No. 2011-0062891 filed with the Korean Intellectual Property Office (KIPO) on Jun. 28, 2011, the contents of which are hereby incorporated by reference in their entirety. technical field [0003] The present disclosure relates to organic light emitting display (OLED) devices and methods of manufacturing organic light emitting display devices. More particularly, certain embodiments relate to organic light emitting display devices including spacers and planarization patterns and methods of manufacturing organic light emitting display devices including spacers and planarization patterns. Background technique [0004] An organic light emitting display (OLED) device may generally include a thin film transistor (TFT), a pixel electrode, a light emitting structure, and a common electrode formed on a substrate. The light emitting structure may include an emission l...
