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： Provided are a liquid crystal display device with horizontal electric field mode, in which a decrease in driving speed can be suppressed by reducing the resistance of a wiring even when the number of pixels is increased, and a manufacturing method thereof. One of a scan wiring and a signal wiring is divided in an intersection portion where the scan wiring and the signal wiring intersect with each other, and the separated wirings are connected with a connection electrode positioned over a thick insulating film. Accordingly, parasitic capacitance at the intersection portion can be reduced, preventing the decrease in the driving speed. The connection electrode is formed at the same time as formation of a pixel electrode and a common electrode using a low-resistance metal, which contributes to the reduction in manufacturing process of the liquid crystal display device.
