An oxide thin film transistor (TFT) and a fabrication method thereof are provided. First and second data wirings are made of different metal materials, and an active layer is formed on the first data wiring to implement a short channel, thus enhancing performance of the TFT. The first data wiring in contact with the active layer is made of a metal material having excellent contact characteristics and the other remaining second data wiring is made of a metal material having excellent conductivity, so as to be utilized to a large-scale oxide TFT process. Also, the first and second data wirings may be formed together by using half-tone exposure, simplifying the process.

A printing plate and a method of fabricating an LCD device are disclosed. The printing plate includes convex and concave portions, and a blanket support formed in the concave portion to prevent the bottom of the concave portion from being directly in contact with a pattern material coated on a blanket of a printing roll. The blanket support is additionally formed in the concave portion of the printing plate to prevent the pattern material coated on the blanket of the printing roll from being directly in contact with the bottom of the concave portion. In this case, the pattern material can be prevented from being transferred onto the printing plate in an undesired pattern. As a result, it is possible to form a precise pattern.

Disclosed is a solvent for printing which comprises a first solvent selected from the group consisting of acetone, methyl ethyl ketone, methyl acetate, ethyl acetate, methanol and mixtures thereof, and a second solvent selected from the group consisting of propylene glycol monomethyl ether acetate (PGMEA), propylene glycol monomethyl ether (PGME), isopropanol, butyl acetate, ethyl-3-ethoxypropionate and mixtures thereof. Further disclosed are a pattern composition for printing comprising the solvent for printing, and a patterning method using the composition. The use of the solvent for printing enables formation of an accurate pattern.

Disclosed are a catalyst for preparing synthesis gas from natural gas and carbon dioxide, and a method for preparing the same. More particularly, a combined reforming process is performed as an economical way of using carbon dioxide, wherein steam reforming of natural gas is carried out simultaneously with carbon dioxide reforming of methane in such a manner that a predetermined ratio of carbon monoxide/carbon dioxide/hydrogen (H2/(2CO+3CO2)=0.85-1.15) is maintained. In this manner, the catalyst is used to prepare synthesis gas suitable for methanol synthesis and Fischer-Tropsch synthesis. Disclosed also is a method for preparing synthesis gas on a specific catalyst consisting of Ni/Ce/MgAlOx or Ni/Ce—Zr/MgAlOx. The catalyst is inhibited from deactivation caused by generation of cokes during the reaction as well as deactivation caused by reoxidation of nickel with water added during the reaction. Therefore, the catalyst shows excellent activity as compared to other catalysts for use in combined reforming.

A method of forming a substrate for an LCD device includes the steps of forming a column spacer pattern in a printing roll, forming an overcoat layer pattern in the printing roll provided with the column spacer pattern, and c) rotating the printing roll on the substrate to simultaneously transfer the overcoat layer pattern and the column spacer pattern onto the substrate. Since both the column spacer pattern and the overcoat layer pattern are formed in one printing roll, the column spacer and the overcoat layer can be formed simultaneously on the substrate through a single transfer process. This reduces the process time and thus facilitates mass production.
