摘要： A liquid crystal display device using a liquid crystal exhibiting a blue phase and having a novel structure, and a method for manufacturing the liquid crystal display device. A plurality of structure bodies (also referred to as ribs, protrusions, or projecting portions) are formed over the same substrate, and a pixel electrode and an electrode (a common electrode at a fixed potential) corresponding to the pixel electrode are formed thereover. An electric field is applied to the liquid crystal layer exhibiting a blue phase by using the pixel electrode that has an inclination and the electrode corresponding to the pixel electrode, which also has an inclination. A shorter distance between the adjacent structure bodies allows a strong electric field to be applied to the liquid crystal layer, which results in a reduction in power consumption for driving the liquid crystal.
