Abstract

Provided are an organic light emitting display device (OLED) and a method of fabricating the same. When a electrically conductive line and a gate electrode are formed at the same time or when a first electrode is formed, interconnections for electrically connecting elements are formed. Thus, the number of used masks can be reduced, so that the overall fabrication process can be shortened and the production cost can be reduced.

Description

technical field [0001] The present invention relates to an organic light-emitting display device (OLED) and a method of manufacturing the same, and more particularly, to an OLED in which when a metal interconnection and a gate electrode are simultaneously formed or when a first electrode is formed, a The interconnection of the connecting elements makes it possible to shorten the overall manufacturing process and reduce the manufacturing cost by reducing the number of masks used. Background technique [0002] Among flat panel display devices (FPD), an organic light emitting display device (OLED) is a light emitting device having a wide viewing angle and a fast response speed of 1 ms or less. In addition, OLEDs can be manufactured in a thin thickness at low cost and have good contrast. [0003] In an OLED having an organic light emitting layer (EML) interposed between an anode and a cathode, holes transported from the anode combine with electrons transported from the cathode ...
