PROBLEM TO BE SOLVED: To obtain contamination preventing property which suppresses deposition of contaminants such as fat and sweat of fingers on a display screen and suppresses deposition of water even when the surface is scratched, by specifying the contact angle of a surface protective layer for water and the volume resistivity of the surface protective layer. SOLUTION: A liquid crystal display element described below is used. A liquid crystal dispersion polymer layer 2 having fine dispersion of at least a liquid crystal in a polymer matrix, and a surface protective layer 1 are successively formed on a conductive layer 6. The contact angle for water of the surface protective layer 1 is specified to >=80 deg. and the volume resistivity of the surface protective layer 1 is >=10<13>Ω.cm at 20 deg.C and 90% relative humidity(RH). The surface protective layer of the liquid crystal display element consists of a transparent and water-repellent polymer having high electric resistance. Namely, the contact angle for water of the surface protective layer is >=80 deg. and its volume resistivity is >=10<13>Ω.cm at 20 deg.C and 90% RH. Moreover, a transparent layer of high electric resistance is preferably formed between the conductive layer 6 and the liquid crystal dispersion polymer layer.
