Abstract: A pattern forming apparatus includes a substrate receiving part on which a printed substrate formed with an organic layer thereon is disposed, and a rotation roll that removes portions of the organic layer to form a pattern. The rotation roll includes a rotation body having a cylindrical shape, a pivot engaged with the rotation body to transfer a rotational force to the rotation body, and a blanket attached to an outer surface of the rotation body. The blanket includes an embossed pattern formed on a surface thereof.
