Abstract
A liquid crystal display element having an improved response speed by using a liquid crystal compound having a high K33, while neither improving nor deteriorating all the characteristics as a liquid crystal display element. The liquid crystal display element 10 of the present invention has a first substrate 15, a second substrate 15′, and a liquid crystal composition layer 5 interposed between the first substrate 15 and the second substrate 15′, wherein at least one of the first substrate 15 and the second substrate 15′ has an electrode that controls the liquid crystal composition layer 5 and the bend elastic constant K33 of at least one kind of liquid crystal compounds in the liquid crystal composition constituting the liquid crystal composition layer 5 is 20 pN or more.
