摘要： A problem exists in that black luminance in a liquid crystal display device when seen in a dark place is high compared to black luminance of a light emitting element in a non-light-emitting state, so as a result, contrast ratio is low. There is a high demand for contrast ratio to be improved. Therefore, it is an object of the present invention to provide a liquid crystal display device with improved contrast ratio and a wide viewing angle. Retardation films and stacked polarizing plates are provided over light transmitting substrates which sandwich a display element. A film having liquid crystal with hybrid oriented liquid crystal, a film having liquid crystal with twisted orientation, uniaxial retardation films, or biaxially retardation films can be used as the retardation films. It is preferable that the stacked polarizing plates comprise two polarizing plates.

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： 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。
