Abstract

Provided are a reflective liquid crystal display device and electronic equipment that appropriately suppress moire fringes. The reflective liquid crystal display device is equipped with a liquid crystal panel and a front light unit, and the liquid crystal panel has: a reflective electrode; a first substrate, which is provided with a reflective electrode; a transparent electrode, which is opposite to the reflective electrode and arranged for every multiple unit pixels; the second a substrate provided with a transparent electrode; a liquid crystal layer provided between the first substrate and the second substrate; and a sheet-shaped anisotropic scattering member laminated on the second substrate in which low-refractive-index regions are mixed and a high-refractive-index region having a higher refractive index than the low-refractive-index region, the front light unit has: a light guide plate that is laminated on the face of the second substrate side of the liquid crystal panel, and multiple grooves with a pitch of less than 100 μm; and a light source that makes light incident to the light guide plate, wherein the pitch of the unit pixel is larger than the average arrangement interval of the high refractive index regions 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...
