Patent ID: 7733447

Claim:
A liquid crystal display device in which three cholesteric liquid crystal layers of selective reflection type are laminated, comprising: a first cholesteric liquid crystal layer arranged on a device observation side selectively reflecting blue; a second cholesteric liquid crystal layer arranged next to the first cholesteric liquid crystal layer selectively reflecting green; a third cholesteric liquid crystal layer arranged next to the second cholesteric liquid crystal layer selectively reflecting red; a green cut filter layer arranged between the second cholesteric liquid crystal layer and the third cholesteric liquid crystal layer selectively absorbing a light ray having a wavelength of 600 nm or less; and a blue cut filter layer arranged between the first cholesteric liquid crystal layer and the second cholesteric liquid crystal layer selectively absorbing a light ray having a wavelength of 520 nm or less, wherein: each liquid crystal layer is sandwiched by two substrates, and the two substrates and the each liquid crystal layer constitute a panel; and the liquid crystal display device comprises two adhesive layers that bond a plurality of panels; wherein at least one of the green cut filter layer and the blue cut filter layer is formed on the liquid crystal layer side of the substrate of the panel and the electrode is formed on at least one of the green cut filter layer and the blue cut filter layer.
