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。

摘要： It is an object of the present invention to suppress light leakage in a dark state which is generated by rubbing treatment. A liquid crystal material containing an ultraviolet curable liquid crystalline monomer at a concentration of more than 0 wt % and not more than 1.0 wt % is used for a liquid crystal layer, and the liquid crystal layer is irradiated with ultraviolet rays. By applying such a liquid crystal layer to a liquid crystal display device, light leakage in a dark state can be suppressed, and the black display can be improved. Therefore, a liquid crystal display device with an excellent contrast and high display quality can be obtained.

摘要： External light is reflected due to a difference in refractive indices of a black matrix and a glass substrate. When the black matrix is a black resin, there is a difference in refractive indices of the black resin and a first substrate. Also, there is a difference in refractive indices of the colored layer and the first substrate. Therefore, external light is slightly reflected. There is a problem in that the reflected light reduces contrast. A structure in which one polarizing element having dichroism is interposed between a pair of substrates is employed, and a light interference layer is provided between a color filter and a glass substrate, whereby a difference in refractive indices is moderated to reduce light reflection.
摘要翻译：由于黑色矩阵和玻璃基板的折射率差异，外部光被反射。当黑色矩阵是黑色树脂时，黑色树脂和第一基底的折射率存在差异。此外，着色层和第一基板的折射率存在差异。因此外部光线稍微反射。反射光有降低对比度的问题。采用其中具有二向色性的一个偏振元件插入在一对基板之间的结构，并且在滤色器和玻璃基板之间设置光干涉层，由此减小折射率差以减少光反射。

摘要： It is an object to provide a liquid crystal display device using a liquid crystal material exhibiting a blue phase which 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 and a common electrode layer having an opening pattern (a slit). An electric field is applied between the pixel electrode layer and the common electrode layer which have opening patterns and are provided so that a liquid crystal is interposed therebetween, whereby an oblique (oblique to a substrate) electric field is applied to the liquid crystal. Thus, liquid crystal molecules can be controlled by the electric field.

摘要： It is an object to provide a liquid crystal display device capable of displaying a moving image with high image quality by employing a time-division display system (also called a field-sequential system) with the use of a plurality of light-emitting diodes (hereinafter referred to as LEDs) as a backlight. Further, it is an object to provide a liquid crystal display device in which high image quality, full color display, or low power consumption is realized by adjustment of the peak luminance. After a liquid crystal layer is sealed between a pair of substrates, polymer stabilization treatment is performed with the use of UV irradiation from both above and below the pair of substrates at the same time, whereby the polymer included in the liquid crystal layer sandwiched between the pair of substrates is evenly distributed. Thus, a liquid crystal display device is manufactured.

摘要： A liquid crystal dripping method has a problem in that an uncured sealant increases in width at the time of attaching a pair of substrates and thus a liquid crystal material enters the sealant and unevenness occurs in the inner periphery of the sealant. A region in which reduced is the speed of diffusion of liquid crystal at the time of attaching a pair of substrates is provided between a sealant and an orientation film. Further, time for diffusing the liquid crystal and coming in contact with the sealant is made long. Accordingly, the sealant is subjected to photo-curing before the liquid crystal comes in contact with the sealant. The region in which reduced is the speed of diffusion of the liquid crystal is formed using a material for forming a vertical orientation film, a silane coupling agent, a substance having a photocatalytic function, or the like.
摘要翻译：液晶滴落方法存在的问题是，在粘附一对基板时未固化的密封剂的宽度增加，因此液晶材料进入密封剂，并且密封剂的内周发生不均匀。在密封剂和取向膜之间设置有在附着一对基板时液晶的扩散速度降低的区域。此外，使液晶扩散和与密封剂接触的时间变长。因此，在液晶与密封剂接触之前，对密封剂进行光固化。使用用于形成垂直取向膜的材料，硅烷偶联剂，具有光催化功能的物质等，形成液晶的扩散速度降低的区域。

In a display device having a display element interposed between a pair of light-transmitting substrates, a stack of polarizer-including layers in a parallel nicol state is provided outside each of the light-transmitting substrates. Here, transmission axes of polarizers that are stacked in the stack on one side of the display element and transmission axes of polarizers that are stacked in the stack on another side of the display element are arranged to be displaced from a cross nicol state. Also, a retardation film may be provided between the polarizers that are stacked and the substrate.
