LIQUID CRYSTAL DEVICE AND ELECTRONIC APPARATUS

Abstract

A liquid crystal device has a plurality of pixels arranged. The liquid crystal device includes a first substrate, a second substrate opposing the first substrate, liquid crystal provided between the first substrate and the second substrate, wires formed on the first substrate, and a reflective layer formed on the first substrate. Each pixel has a reflective display region formed by the reflective layer and a transparent display region without the reflective layer, and each wire is routed between two pixels in the transparent display region and in the reflective display region.
