Abstract:
An optical sheet is comprised of an optical film (12a, 12b, 12c) laminated onto an adhesive layer (18a, 18b, 18c). The perimeter of the adhesive layer is inset from the perimeter of the optical film. Multiple optical films may be stacked onto each other to form an optical sheet set (10) that efficiently assembles into an optical display. The optical sheet set (10) has no exposed adhesive, which tends to collect dust and particles or transfer to other parts of display.
