A planar light source device includes a light diffusing portion and a light reflecting portion in this order. The light diffusing portion has light transmissivity and light diffusivity. Reflectance of the light reflecting portion with respect to light of a particular wavelength entering at an angle of incidence of 0° is 80% or higher. The reflectance of the light reflecting portion with respect to at least part of light of the particular wavelength entering at an angle of incidence of which an absolute value is greater than 45° is less than 50%.
