Abstract:
A display apparatus includes: a light guide plate; a light source that causes light to be incident on an end surface of the light guide plate; a hiding plate that is provided on a side of an emission surface of the light guide plate, and that includes a light transmission part which transmits light emitted from the emission surface and a light shielding part which has lower light transmittance than the light transmission part; and a colored board that has light reflectance closer to light reflectance of the light shielding part than light reflectance of the light transmission part in each wavelength, and that is provided on a side of a reflection surface of the light guide plate so as to overlap the light transmission part of the hiding plate when viewed from a direction perpendicular to the emission surface of the light guide plate.
