Abstract:
A method for forming a micro-retarder plate, comprising:providing a plate with phase retardation having a first surface and a second surface; laminating a first protection layer on the first surface of the plate with an index-matching glue layer; patterning the plate with phase retardation to form a micro-retarder with a plurality of first retardation state areas and a plurality of second retardation state areas alternating with each other, wherein linear polarized lights with direction of polarization being 45 degrees to the stretching direction of the retardation film passing through the first retardation state areas and the second retardation state areas are perpendicular to each other; and laminating a second protection layer on the second surface of the micro-retarder with a second index-matching glue layer.
