Abstract
An object is to provide a liquid crystal display device using a liquid crystal material exhibiting a blue phase, in order to enable a higher contrast. In a liquid crystal display device which includes a liquid crystal layer exhibiting a blue phase, a first structure body and a second structure body are provided over a first electrode layer (a pixel electrode layer) and a second electrode layer (a common electrode layer), respectively. The first structure body and the second structure body are insulators each having a higher dielectric constant than a liquid crystal material used for the liquid crystal layer, and are provided to project into the liquid crystal layer.
