Abstract: 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.
