Abstract:
The present invention provides a thin optical laminated sheet with little or no interference fringes or iris-like colors, and a method of manufacturing the optical laminated sheet. An optical laminated sheet is integrally formed by laminating a plurality of optical films having an adhesive layer interposed therebetween, the optical laminated sheet including an adhesive layer A wherein one surface is a flat and smooth surface and the opposite surface has an unevenness shaped by a transfer. The optical laminated sheet may include an integrally formed laminate wherein one surface of the adhesive layer A is planarly bonded to one surface of the optical film and an uneven surface that is the other surface of the adhesive layer A is linearly and/or intermittently bonded to the prism edges of a light collecting film made up of prism rows. The optical laminated sheet may be used in a backlight unit.
