Embodiment Construction

[0015] The present invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments are shown. The embodiments may take various forms and should not be construed as being limited to the specific embodiments set forth herein. For clarity, the thickness of the regions or layers shown in the drawings are exaggerated. Throughout the specification, the same reference numerals are used to denote the same elements.

[0016] Figure 3C Is a cross-sectional view of a unit pixel of an organic light emitting display (OLED) according to the first exemplary embodiment. reference Figure 3C , A thin film transistor (TFT) "E" including a semiconductor layer 210, a gate electrode 220, a source electrode 230a, and a drain electrode 230b is disposed on the substrate 200. An insulating layer (not shown) is provided on the TFT "E". The insulating layer may include one or more inorganic layers, and / or one or more organic layers.

Abstract

In one embodiment, the present invention provides an organic light-emitting display (OLED), which includes: a TFT disposed on a substrate; an insulating layer disposed on the TFT and having a through hole; disposed on the insulating layer and connected through the through hole a pixel electrode to a drain electrode of the TFT; an emission layer disposed on the pixel electrode; and a counter electrode pattern disposed on the emission layer and exposing at least an upper portion of the through hole. This avoids the close structural proximity between the counter electrode and the pixel layer, thereby reducing the possibility of short circuits.

Description

Technical field [0001] The present invention relates to an organic light emitting display (OLED) and a manufacturing method thereof, and more particularly, to an OLED and a manufacturing method thereof, which can basically prevent a short circuit between a pixel electrode and a counter electrode. Background technique [0002] Organic light emitting displays (OLEDs) are very suitable for displaying moving images regardless of their size, because OLEDs have a fast response speed of 1ms or less, low energy consumption, and are emissive display elements, so they have Wide viewing angle. In addition, OLEDs can be manufactured at low temperatures and in a simple process based on traditional semiconductor manufacturing technology. For these reasons, OLED has attracted much attention as a next-generation flat panel display (FPD) component. [0003] figure 1 It is a cross-sectional view of a unit pixel of a traditional OLED. [0004] reference figure 1 The pixel electrode 150 of the OL...
