Light guide plate stamp and method of manufacturing the same
A stamp includes a metal supporting layer, a pattern forming layer and an adhesive layer. The metal supporting layer has a first thermal conductivity. The pattern forming layer is disposed on the metal supporting layer and has a surface with a molding pattern formed thereon. The adhesive layer is disposed between the metal supporting layer and the pattern forming layer to couple the pattern forming layer to the metal supporting layer, and has a second thermal conductivity lower than the first thermal conductivity. Thus, strength of the stamp may be improved, and deformation of the stamp during the process of manufacturing a light guide plate may be reduced or prevented.
