<p>The present invention provides a light guide plate having an input surface for receiving light from a light source, a micro-patterned output surface for emitting light, and a micro-patterned bottom surface opposing to the output surface. The invention provides extruding a resin into the nip between a first patterned roller and a second patterned roller at a first patterned roller surface temperature T1, a second patterned roller temperature T2, and a nip pressure P1, to form an optical sheet, the optical sheet having a first patterned surface and a second patterned surface, the first patterned surface having a pattern transferred from the first patterned roller and the second patterned surface having a pattern transferred from the second patterned roller, and cutting and finishing the said optical sheet into a plurality of double-sided light guide plates having the specified length and width dimensions.</p> |
