Claim Text:
1. A method for producing a masterboard alignment film comprising: coating an alignment solution on a masterboard having two or more substrates using a transfer printing plate which has a transfer region simultaneously covering the two or more substrates, so that the alignment solution forms an alignment film on the masterboard; and removing the alignment film on the masterboard which is located in regions that are out of display regions of the substrates and where there is no need to retain the alignment film; wherein the alignment film is formed of a light processing material comprising a liquid crystal molecule alignment material, a photosensitive material, a photosensitizer and a solvent; and an exposure process is conducted on the alignment film itself using a mask plate with a duration of exposure being between 60 seconds and 100 seconds so as to make a predetermined region of the alignment film exposed, and then a developing process is conducted on the alignment film itself for removing the alignment film in regions that are out of display regions of the substrates and where there is no need to retain the alignment film; wherein the transfer printing plate is provided around an outer surface of a roll, and the transfer printing plate comprises a basal membrane and a transfer layer that is smaller than the basal membrane and disposed on the basal membrane, and in operation the transfer layer simultaneously contacts the two or more substrates of the masterboard to simultaneously transfer the alignment solution onto the two or more substrates of the masterboard.
