Abstract
A liquid crystal display device using a liquid crystal material exhibiting a blue phase is provided to achieve higher contrast. Further, the power consumption of the liquid crystal display device using a liquid crystal exhibiting a blue phase is reduced. In a liquid crystal display device including: a first substrate provided with a pixel electrode layer (also referred to as a first electrode layer); and a second substrate provided with a common electrode layer (also referred to as a second electrode layer), between which a liquid crystal layer exhibiting a blue phase is interposed, the pixel electrode layer and the common electrode layer project into the liquid crystal layer and are arranged so that the adjacent pixel electrode layer and common electrode layer engage with each other at a distance with the liquid crystal layer interposed therebetween.
