Disclosed is a method of fabricating a display device. The method includes providing a substrate in which a display region and a pad region formed around the display region are defined, forming a conductive layer on the substrate, forming a mask pattern by rolling a roller on the conductive layer, and patterning the conductive layer using the mask pattern to form a line in the display region and a pad in the pad region. The pad is formed of a pattern having a second width corresponding to a first width of the line.

Disclosed is a method for fabricating a cliché that can prevent formation of a defective thin film pattern, and a method for forming a thin film pattern using the same. The method for fabricating a cliché includes providing a base substrate having first and second regions, forming a first depressed pattern having a first depth and a first width at a first region, and a second depressed pattern having a second width greater than the first width and a depth the same with the first depth at a second region, forming a protective film for exposing the second region and covering the first region, the protective film having adhesivity, forming the second depressed pattern to have a second depth deeper than the first depth of the first depressed pattern at the first region by using the protective film having the adhesivity, and removing the protective film.

A method for fabricating an LCD includes: providing a substrate with a thin film transistor (TFT) part defined thereon; forming a metallic film for a gate electrode on the substrate; etching the metallic film through a first printing process to form a gate electrode; sequentially forming a gate insulating layer, a semiconductor layer, and a metallic film for source and drain electrodes on the substrate; selectively etching the metallic film for source and drain electrodes, the semiconductor layer and the gate insulating layer through a second printing process to form a gate insulating layer pattern, a preliminary active pattern and a metallic film pattern which are sequentially stacked such that the gate insulating layer pattern is over-etched from the side of the preliminary active pattern; forming an insulating layer on the substrate with the metallic film pattern; etching the insulating layer to expose the metallic film pattern; forming a transparent conductive film on the metallic film pattern and a remaining insulating film; and selectively etching the transparent conductive film, the metallic film pattern, the preliminary active pattern to form an active pattern, a source electrode, a drain electrode, and a pixel electrode connected with the drain electrode.

An alignment key, a method for fabricating the alignment key, and a method for fabricating a thin film transistor substrate using the alignment key are provided. The alignment key includes a base substrate, a first alignment key and a first mark portion of a second alignment key, which are formed on the base substrate using a printing roll, a dielectric that is formed on the base substrate to cover the first alignment key, and a second mark portion of the second alignment key, which is formed on the dielectric and at least partly overlaps the first mark portion of the second alignment key.

Provided are a roller apparatus, a printing method and a method of fabricating an LCD device using the same, which can minimize the number of processes and a printing defect. In the printing method, first patterns are formed on a blanket. The first patterns have different surface energy from that of the blanket, and the blanket is formed around a roller. The roller is rotated and a printing material is dropped to form second patterns on the blanket between the first patterns. The second patterns are transferred from the roller onto a substrate.
