Patent ID: 7719646

Claim:
A liquid crystal display device, comprising: a reflecting layer for reflecting incident light; a liquid crystal layer provided on said reflecting layer, in which alignment of liquid crystal molecules is vertical; and a retardation plate and a polarizing plate provided on a front surface of said liquid crystal layer, wherein said reflecting layer has projections and depressions formed on a surface thereof, an average tilt angle of the projections and depressions being a value of not less than 4° nor greater than 6°, and wherein said retardation plate has a negative refractive index anisotropy in a vertical direction to a surface thereof, birefringence in a direction of the thickness, a ratio between a retardation Rf thereof and a retardation Rlc of said liquid crystal layer, Rf/Rlc, being a value of not less than 0.6 nor greater than 0.9.
