Title:
液晶表示装置
Document Type and Number:
Japanese Patent JP4412441
Kind Code:
B2
Abstract:
A liquid crystal display device comprising a first polarizing sheet(16a), a color filter layer(6) formed on glass sheet(18), a second polarizing sheet(16b), three-layered HPDLC(17) formed below the liquid crystal layer(1) and acting as a reflective structural layer having a reflectivity changed electrically, and a backlight unit as the lowermost layer. Each layer of the three-layered HPDLC(17) is composed of a liquid crystal droplet layer polymer layer and reflects blue, green, red by Bragg reflection. When voltage is applied to the three-layered HPDLC(17), the reflectivity of liquid crystal droplet layer of each layer change, so that the HPDLC can be made transparent by equalizing the reflectivities of the liquid crystal liquid droplet layer to those of polymer layers.
