Embodiment Construction

[0038] Reference will now be made in detail to the exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals indicate like elements throughout. In the drawings, the thickness of layers, films, and regions are exaggerated for clarity. The following embodiments are described by referring to the figures in order to explain the present invention, however, the exemplary embodiments and figures are only to illustrate the present invention and are not intended to limit the scope of the present invention.

[0039] In the following description, if a layer is said to be formed "on" another layer, one or more intermediate layers may be disposed between the two layers, or the two layers may be in direct contact with each other. In other words, it will be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" another element, it can be directly on the othe...

Abstract

Disclosed are a display device and method for manufacturing same. The display device comprises an insulating substrate; a source electrode and a drain electrode on the insulating substrate and separated from one another to define a channel region; a wall having one or more openings to expose the channel region, at least a portion of the source electrode, and at least a portion of the drain electrode; and an organic semiconductor layer formed in the one or more openings, the one or more openings comprising a channel part exposing the channel region and an ink guide part extending outward from the channel part. The ink-jet printing process for the display device has an improved processing margin.

Description

technical field [0001] The present invention relates to a display device and a manufacturing method thereof, and more particularly, to a display device including an organic semiconductor layer and a manufacturing method thereof. Background technique [0002] Several types of flat panel display devices are available such as Liquid Crystal Displays LCD, Organic Light Emitting Diode Displays OLED, etc. [0003] The LCD includes an LCD panel having a substrate providing thin film transistors TFTs of TFTs, a color filter substrate providing color filters, and a liquid crystal layer disposed between the two substrates. [0004] The TFT substrate includes a plurality of TFTs that serve as switching and driving elements to control and drive associated pixels. Each TFT includes a semiconductor layer generally employing amorphous silicon or polycrystalline silicon. Recently, an organic semiconductor material has been used as the semiconductor layer. [0005] Organic semiconductor (...
