Title: Photosensitive resin plate with polyimide pattern edge portion having greater hardness than polyimide pattern portion

Abstract: An APR plate includes a polyimide(PI) pattern portion having a first hardness and corresponds to an effective screen area of an LCD panel and a PI pattern edge portion having a second hardness that is greater than the first hardness and corresponds to a non-effective screen area of the LCD panel. Associated methods of forming the dual-hardness resin plate and methods and apparatus of fabricating an orientation layer on a LCD panel include APR resin plates configured to yield uniform PI layers and inhibit PI lump generation even after the APR plate is repeatedly used in printing.
