摘要：
A liquid crystal display device in which three cholesteric liquid crystal layers of selective reflection type are laminated, comprises: a first liquid crystal layer arranged on a device observation side selectively reflecting blue; a second liquid crystal layer arranged next to the first liquid crystal layer selectively reflecting green; a third liquid crystal layer arranged next to the second liquid crystal layer selectively reflecting red; and a green cut filter layer arranged between the green liquid crystal layer and the red liquid crystal layer selectively absorbing a light ray of a wavelength of 600 nm or less.
