    摘要: A method of forming an optical compensation film includes coating one or more first layers and one or more second layers onto a carrier substrate, and stretching the first layers and second layers simultaneously. The one or more first layers include a polymer having an out-of-plane birefringence (Δnth) not more negative than −0.005 and not more positive than +0.005, and the one or more second layers include a polymer having an out-of-plane birefringence more negative than −0.005 or more positive than +0.005. The overall in-plane retardation (Rin) of the optical compensation film is greater than 20 nm and the out-of-plane retardation (Rth) of the optical compensation film is more negative than −20 nm or more positive than +20 nm.

    摘要: The present invention provides an optical sheet having a plurality of light guide plate patterns, each light guide plate pattern having a micro-patterned output surface for emitting light, and a micro-patterned bottom surface opposing to the output surface. The optical sheet is made in steps comprising: extruding a resin into the nip between a patterned roller and a patterned carrier film at a patterned roller temperature T1 and a nip pressure P1, to form the optical sheet, the optical sheet having a first patterned surface and a second patterned surface, the first patterned surface having a micro-pattern transferred from the patterned roller and the second patterned surface having a micro-pattern transferred from the patterned carrier film; and peeling off the patterned carrier film from the optical sheet.
