Abstract
An object is to provide a liquid crystal display device which includes a liquid crystal material exhibiting a blue phase and enables higher contrast. In the liquid crystal display device including a liquid crystal layer exhibiting a blue phase, the liquid crystal layer exhibiting a blue phase is interposed between a pixel electrode layer having an opening pattern (slit) and first and second common electrode layers which face each other and have opening patterns. The pixel electrode layer is formed over a structure body which projects into the liquid crystal layer from a surface of a first substrate on the liquid crystal layer side, and the pixel electrode layer is positioned between the first common electrode layer and the second common electrode layer in the liquid crystal layer. The cell gap of the liquid crystal display device is less than 5 μm (preferably 1 μm or more).
