Abstract

An organic thin film transistor, a method of manufacturing the same, and a display device using the same are provided. The organic thin film transistor includes a source and a drain on a substrate, reverse taper-shaped banks that are positioned on the source and the drain to expose a portion of each of the source and the drain, and an organic semiconductor layer between the reverse taper-shaped banks.

Description

Technical field [0001] The embodiment relates to an organic thin film transistor and a method of manufacturing the same, and a display device using the thin film transistor. Background technique [0002] This application claims the priority of Korean Patent Application No. 10-2008-113619 filed on November 14, 2008, the entire content of which is incorporated herein by reference. [0003] With the development of information technology, display devices have been widely used as a connection medium between users and information. As a result, the use of flat panel displays such as liquid crystal displays (LCD), organic light emitting diode (OLED) displays, and plasma display panels (PDP) is gradually increasing. In flat panel displays, because liquid crystal displays can achieve high resolution and can be manufactured as large-size displays and small-size displays, they are widely used. [0004] Some display devices are driven by thin film transistors to display images. The thin film t...
