A light guide plate for image display can display clear images even when a resin base is used. The Sight guide plate configured for image display may include a first resin base and a hologram layer. The first resin base may have an MC value of 0.120 or less, obtained by evaluation using shadow contrast, according to expression (1): wherein Lmax is a maximum value of brightness from a brightness distribution, Lmin is a minimum value of the lightness 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.

Light guide plate for image display

A monoamine compound characterized by being represented by the following general formula (1). [In general formula (1), Rto Reach independently represent a phenyl group which may have a substituent in at least one of o- and m-positions, in which the substituent may be bonded to each other to form a cyclic structure. Rto Rare a group different from each other.]
