摘要： A reflection type liquid crystal display device according to the present invention is constructed to include: a light modulation layer having a light scattering state changed when a voltage is applied between electrode faces; at least one kind of color separation layer arranged at the back of the liquid crystal; and a reflection layer arranged at the back of the color separation layer. The light modulation layer is a polymer network type polymer scattered liquid crystal layer or a phase conversion type liquid crystal layer, and the color separation mirror is a cholesteric liquid crystal polymer layer or a dielectric multi-layered thin film characterized to reflect a light within a predetermined wavelength range in the visible light region selectively. A reflection preventing layer and an ultraviolet ray cut-off layer are further arranged on the surfaces of the electrode faces.

摘要： A reflection type liquid crystal display device comprises a pair of substrates having electrodes, a light scattering type liquid crystal layer interposed between the substrates, a reflection layer disposed over a rear surface of the light scattering type liquid crystal layer, and a light absorbing layer disposed over a rear surface of the reflection layer for absorbing a light passed through the reflection layer. The light scattering type liquid crystal layer changes into a scattering state or a transparent state in accordance with a change in a voltage level between the electrodes, and transmits 60% or more of incident light irrespective of the change in the voltage level between the electrodes. The reflection layer has a reflectivity within a range of 10 to 50% for reflecting a forward scattered light passed through the light scattering type liquid crystal layer.
