<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of a light guide plate in which void generation between a reflection plane for extracting image light and a resin for burying the reflection plane or the like is suppressed and in a see-through type light guide plate, a transmission image can be prevented from blurring. <P>SOLUTION: A resin material PM positioned at the deepest side of a sawtooth-shaped part DT is preferentially cured to avoid void generation between the resin material and a reflection membrane MB and to maintain optical characteristics of the reflection membrane MB, namely, of reflection planes 23a and 23b excellent, thereby improving a definition of a light guide plate 20. Furthermore, by suppressing cyclic swell occurrence caused by shrinkage on a surface, a front face FF having desired flatness can be formed in a flattening step that is a final step of manufacturing an ultraviolet-curable resin member Qa. Therefore, when using the light guide plate 20 as a see-through type, an outer field image is prevented from being blurred or disturbed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
