Apparatus and method for manufacturing polarizing film, and liquid crystal cell and method for manufacturing the same

The present invention provides an apparatus for manufacturing a polarizing film of a liquid crystal display, which is not time-consuming and does not require much labor to manufacture the polarizing film and proceed the adhering operation, as required in the prior arts. The dichroism dye solution developed by Optiva Inc. is served as the ink, which is printed onto the glass or plastic substrate via the flexography device to manufacture the polarizing film. As shown in the drawing, a plate (1) having a plurality of grooves (a) is installed on the plate body (2) along the printing direction. The ink drops paralleling to the clockwise-rotating plate (1) from the distributor (3), and is applied and spreaded with a knife (4). The dichroism dye in the liquid crystal state is filled into the grooves (a); meanwhile, the knife (4) is not in touch with the plate (1), instead, with a gap therebetween, and an ink film is formed on the plate surface. Therefore, upon the glass substrate (6) secured on the table (5) passing
