Abstract
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.

A method of forming a substrate for an LCD device comprising the steps of:
- a) forming a column spacer pattern on a printing roll;
- b) forming an overcoat layer pattern on the printing roll overlying 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.
A method of forming a substrate for an LCD device comprising the steps of:
- forming a light-shielding layer and a color filter layer on the substrate;
- forming a column spacer pattern on a printing roll;
- forming an overcoat layer pattern on the printing roll overlying the column spacer pattern;
- and
- rotating the printing roll on the substrate to simultaneously transfer the overcoat layer pattern and the column spacer pattern onto the substrate,
- wherein the column spacer pattern overlies the overcoat layer and is substantially aligned with the light-shielding layer.
