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.

摘要： An object is to provide a highly reliable liquid crystal display device which includes a liquid crystal layer exhibiting a more stable blue phase. Another object is to provide a method for manufacturing a liquid crystal display device with high yield. Polymer stabilization treatment is performed as follows: a photocurable resin is added to a liquid crystal material exhibiting a blue phase, and the photocurable resin is selectively polymerized by scanning a liquid crystal layer provided between a first substrate and a second substrate with light in a certain direction. Thus, a first region where the light irradiation treatment is performed and a second region where the light irradiation treatment is not performed are formed in the liquid crystal layer. Since polymerization of the photocurable resin proceeds in the first region, the polymerization degree of the photocurable resin in the first region is higher than that in the second region.
摘要翻译：本发明的目的是提供一种高度可靠的液晶显示装置，其包括具有更稳定的蓝相的液晶层。另一个目的是提供一种以高产率制造液晶显示装置的方法。聚合物稳定化处理如下进行：在具有蓝相的液晶材料中添加光固化性树脂，通过用特定的光扫描设置在第一基板和第二基板之间的液晶层，选择性地聚合光固化树脂方向。因此，在液晶层中形成进行光照射处理的第一区域和不进行光照射处理的第二区域。由于在第一区域中进行光固化树脂的聚合，所以第一区域中的光固化性树脂的聚合度高于第二区域。
