Liquid crystal display device

A liquid crystal display device comprising:

• a first substrate provided with a first electrode layer;
• a second substrate provided with a second electrode layer;
• and
• a liquid crystal layer including a liquid crystal material exhibiting a blue phase between the first substrate and the second substrate,
• wherein the first electrode layer and the second electrode layer project into the liquid crystal layer with the liquid crystal layer interposed therebetween,
• wherein a distance between the first electrode layer and the second electrode layer is a distance at which a liquid crystal in the liquid crystal layer between the first electrode layer and the second electrode layer responds to a voltage applied to the first electrode layer and the second electrode layer, and
• wherein sum of a maximum film thickness of the first electrode layer and a maximum film thickness of the second electrode layer is greater than a maximum thickness of the liquid crystal layer.

A liquid crystal display device comprising:

• a first substrate and a second substrate between which a liquid crystal layer including a liquid crystal material exhibiting a blue phase is interposed;
• a rib-shaped first structure body which projects into the liquid crystal layer from a surface of the first substrate on the liquid crystal layer side;
• a rib-shaped second structure body which projects into the liquid crystal layer from a surface of the second substrate on the liquid crystal layer side;
• a first electrode layer which covers top and side surfaces of the rib-shaped first structure body;
• and
• a second electrode layer which covers top and side surfaces of the rib-shaped second structure body,
• wherein the first electrode layer and the second electrode layer are arranged with the liquid crystal layer interposed therebetween, and
• wherein sum of a maximum film thickness of the rib-shaped first structure body and a maximum film thickness of the rib-shaped second structure body is greater than a maximum thickness of the liquid crystal layer.
