PROBLEM TO BE SOLVED: To provide a reflection type liquid crystal display device utilizing selective reflection of a cholesteric liquid crystal or a chiral nematic liquid crystal, which has a high response to a voltage change, has a low viscosity, and is not easily deteriorated by ultraviolet rays. Provided is a liquid crystal display device using the same. SOLUTION: In a reflection type liquid crystal display device using selective reflection of cholesteric liquid crystal or chiral nematic liquid crystal, a layer having an ultraviolet cut function is formed on a side surface on which external light is incident. The liquid crystal is at 20 ° C, It is desirable to use a liquid crystal display element having a viscosity of 40 mPa · s or less. |
