Abstract: 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.

Abstract translation: 使用具有蓝相的液晶并具有新颖结构的液晶显示装置，以及液晶显示装置的制造方法。 在同一基板上形成多个结构体（也称为肋，凸部或突出部），并且在其上形成像素电极和与像素电极对应的电极（固定电位的公共电极）。 通过使用具有倾斜度的像素电极和对应于也具有倾斜度的像素电极的电极，向呈现蓝相的液晶层施加电场。 相邻的结构体之间的较短的距离允许将强电场施加到液晶层，这导致用于驱动液晶的功耗的降低。
