Abstract: Printing unevenness caused in forming a polarizing film by printing an ink liquid having a dichromatic dye is minimized to provide satisfactory LCD display characteristics. Bearings are erected on opposite sides of a table and are formed with vertical slots, into which the opposite ends of an axle of a printing cylinder are dropped, whereby the axle of the printing cylinder is loosely fitted in the right and left bearings. The bearings are horizontally movably constructed and connected to a horizontal motion drive (not shown). Further, right and left weights of equal heaviness are attached to the opposite sides of the axle of the printing cylinder. In producing a polarizing film, a substrate is placed on the table and a format having a number of fine grooves is attached to the printing cylinder and placed on the substrate. Ink liquid having a dichromatic dye is applied to the format to form a thin film of ink liquid on the format surface, and the bearings are horizontally moved along the printing direction.
