| 17. 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 an entire surface of 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
having a different shape from the overcoat layer pattern onto the substrate,
wherein the column spacer pattern overlies the overcoat layer and is substantially aligned with the light-shielding layer;
wherein forming the column spacer pattern on the printing roll comprises depositing a spacer material on the printing roll
using a printing device, and rotating the printing roll on a printing plate, the printing plate having a spacer pattern thereon.
