Abstract

A plurality of reflection films are provided behind a liquid crystal layer of a liquid crystal element, corresponding to predetermined regions in the plural pixels Pix. By the regions of the plural pixels wherein the reflection films are provided, reflection parts Pr are formed that reflects the light that enters from the front side and goes out to the front side by the region where the reflection film is provided, and transmission parts are formed that transmits the light that enters from the back side and goes out to the front side by the other regions of the plural pixels. At the same time, color filters, wherein a plurality of apertures are formed to the parts corresponding to the reflection pars Pr of the pixels Pix, are provided respectively corresponding to the plural pixels Pix, and a planarization transparent film covering the aperture is formed on these color filters.

Description

technical field [0001] The invention relates to a liquid crystal display device capable of displaying both reflective display and transmissive display. Background technique [0002] As a liquid crystal display device, there are proposed reflective / transmissive liquid crystal display devices that perform both reflective display using external light using ambient light and transmissive display using illumination light from a light source disposed on the rear side. [0003] As such a liquid crystal display device, as disclosed in JP-A-11-264964, a liquid crystal layer is provided between a front substrate on the display viewing side and a rear substrate facing the front substrate. At least one electrode is provided on one of the opposing inner surfaces of the side substrate and the rear substrate, and a plurality of electrodes are provided on the other inner surface for forming a plurality of pixels in a region opposed to the at least one electrode. On the side of the liquid c...
