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.

Description

technical field [0001] The present invention relates to a reflective liquid crystal display device and electronic equipment having the reflective liquid crystal display device. Background technique [0002] In addition to transmissive displays, which display using transmitted light from a backlight on the back of the screen, there are also reflective displays, which display using reflected light from external light. The reflective display has the characteristics of low power consumption and easy to see the screen in a bright environment. [0003] In addition, reflective displays are also equipped with front light units that allow light to enter from the side of the image display surface so that they can be used in locations with little or no external light (see Patent Documents 1 and 2). For example, Patent Document 1 describes a front lighting device provided with a light guide body having an incident part through which light is incident from a light source and a The ligh...
