Abstract
According to an aspect, a reflective liquid-crystal display device includes a liquid-crystal panel and a front light unit. The liquid-crystal panel includes a sheet-like anisotropic scattering member having low refractive index areas and high refractive index areas with a refractive index higher than that of the low refractive index areas. The front light unit includes a light guide plate laminated on the liquid-crystal panel and having a number of grooves formed on a surface facing the liquid-crystal panel at a pitch of equal to or smaller than 100 □m and a light source that makes light incident on the light guide plate. An arrangement interval of the unit pixels is larger than an average of an arrangement interval of the high refractive index area of the anisotropic scattering member.
