Abstract
Embodiments of the present invention disclose a method for producing a masterboard alignment film, and a transfer printing plate and an alignment solution. The method comprises coating the alignment solution on a masterboard having two or more substrates using the 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 the display regions of the substrates and where there is no need to retain the alignment film. This method can solve the existing display defect issues that are caused by too thick peripheral regions of the alignment film, and the overlapping of the too thick peripheral regions of the alignment film with the sealant region.
