Printing device and method for pattrning thin layer using the same

A printing apparatus and a thin film patterning method using the same are provided to attach plural blankets at every printing roller, thereby preventing the lowering of the yield due to the badness. A print roller(120) rotates on a substrate and forms a thin film. An organic solution for forming the thin film is filled with a blanket(130). The blankets are attached to the print roller. The blanket includes a filling groove for filling the organic solution. Plural partitions form the filling grooves. Plural active areas with the same size are formed on the substrate. The width of the filling groove(122) is wider than that of the active area. The plural partitions(124) include the first partitions arranged in parallel to each other. The second partitions are connected with the first partitions. A combining member is formed at the second partition with a step shape or a slant shape. The second partitions also are formed at the edge area of the print roller so that the filling grooves are connected.
