Light guide plate for image display

Abstract

A light guide plate may be configured for image display. Such a light guide plate may include: a first resin base; and a hologram layer, wherein the first resin base may have an MC value of 0.120 or less, the MC value being obtained by evaluation using shadow contrast by Expression (1): MC = L ⁢ max - L ⁢ min L ⁢ max + L ⁢ min . ( 1 ) wherein Lmax is a maximum value of brightness from a brightness distribution, Lmin is a minimum value of the brightness from the brightness distribution, and MC is an MC value that objectively represents a magnitude of a dip in low brightness portions in the brightness distribution. The first resin base may be manufactured by performing cutting and polishing processing.
