  • Publication number: 20140057200
    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.

  • Publication number: 20110013132
    Abstract: A liquid crystal display (LCD) panel, comprising a first substrate and a second substrate assembled face to face, each having a display area and a peripheral area around the display area, liquid crystal, and sealant formed between the peripheral area of the first substrate and the peripheral area of the second substrate. On the first substrate, at least one first obstructing frame is formed between the sealant and the display area of the first substrate; on the second substrate, at least one second obstructing frame is formed between the sealant and the display area of the second substrate; the first obstructing frame and the second obstructing frame are disposed at an interval and parallel to each other; each of the first obstructing frame and second obstructing frame has a thickness smaller than a cell gap, and a sum of the thicknesses of a pair of the first obstructing frame and second obstructing frame that are adjacent to each other is greater than the cell gap.
