1. A light guide plate, comprising:
a glass plate; and
a resin layer formed on at least one surface of the glass plate,
wherein the resin layer includes a resin and metal oxide fine particles dispersed in the resin, an absolute value of a refractive index difference between the glass plate and the resin layer is 0.07 or smaller over an entire wavelength range of 430 nm to 700 nm, the glass plate has a glass composition that satisfies, in mol % in terms of oxides, {(La2O3+Gd2O3+Y2O3+ZrO2+Ta2O5)/(La2O3+Gd2O3+Y2O3+ZrO2+Ta2O5+WO3+Nb2O5+TiO2+Bi2O3)}>0.1, and the metal oxide fine particles comprise at least one oxide selected from the group consisting of lanthanum oxide, gadolinium oxide, yttrium oxide, zirconium oxide, tantalum oxide, and hafnium oxide.
