Patent ID: 8488087

Claim:
A liquid crystal display device, comprising a reflection area within a pixel unit by corresponding to at least to a reflection plate forming part, wherein: the reflection area is driven with a lateral electric field mode and normally-white; and a driving electrode for forming an electric field to a liquid crystal layer of the reflection area is formed on the reflection plate via an insulating film by using a non-transparent electric conductor, an antireflection layer is on a top face of the driving electrode, wherein the antireflection layer is formed with an oxide of an element selected from Cr, Ni, Mo, Zn, and Ti, or with an oxide of an alloy containing an element selected therefrom, and with ITO, and the antireflection layer has refractive index n in a range of “n=1.5-3.0” and extinction coefficient k in a range of “k=0-3.5” at a wavelength of 550 nm; said liquid crystal display device further comprising, within a unit pixel, a transmission area, wherein the transmission area is driven with a lateral electric field mode, and a reflection common electrode of the reflection area and an ITO-covered transmission common electrode of the transmission area, wherein each of the reflection common electrode and the ITO-covered transmission common electrode is connected to a different signal source from each other.
