POLARIZING FILM PRODUCING DEVICE

Printing unevenness caused in forming a polarizing film by printing an ink liquid of dichromatic dye is minimized to provide satisfactory LCD display characteristics. Bearings (8, 8) are erected on opposite sides of a table (5) and are formed with vertical slots (9, 9), into which the opposite ends of an axle (10) of a printing cylinder (2) are dropped, whereby the axle (10) of the printing cylinder (2) are loosely fitted in the right and left bearings (8, 8). The bearings (8, 8) are horizontally movably constructed and connected to a horizontal motion drive (not shown). Further, right and left weights (11, 11) of equal heaviness are attached to the opposite sides of the axle (10) of the printing cylinder (2). In producing a polarizing film, a substrate (6) is placed on the table (5) and a format (1) having a number of fine grooves (a) is attached to the printing cylinder (2) and placed on the substrate (6). And the ink liquid of dichromatic dye is applied to the format (1) to form a thin film of ink liquid on the format surface, and the bearings (8, 8) are horizontally moved along the printing direction. Thereby, the printing cylinder (2) rolls on the substrate (6), so that the thin film of ink liquid is transferred from the format (1) to the substrate (6).
