摘要： A display device with a higher contrast ratio is provided. The display device is provided with stacked polarizing plates arranged displaced from a parallel nicol state. Moreover, in the display device, at least one of a pair of stacked polarizing plates is displaced from a parallel state. The pair of stacked polarizing plates is arranged in a cross nicol state. A retardation plate may be provided between the polarizing plate and the substrate. As a result, the contrast ratio can be increased.

摘要： It is an object to provide a display device with the high contrast ratio by an easy method. In addition, it is an object to provide such a high performance display device at low cost. In a display device including a display element between a pair of light transmitting substrates, a layer including stacked polarizers is each provided on an outer side of the substrates. At that time, the stacked polarizers on a viewing side are arranged to deviate from a parallel nicol state. In addition, a retardation film may be provided between the stacked polarizers and the substrate.

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： 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。

摘要： In a method for manufacturing a liquid crystal display device in which a liquid crystal layer is formed by dropping liquid crystal by a dropping method, a surface of a sealant which is formed over a first substrate is cured by a first cure treatment before dropping the liquid crystal, and then the liquid crystal is dropped. A second substrate has a plurality of projections in a sealant adhesive region. The first substrate and the second substrate are attached to each other with the liquid crystal interposed therebetween so that the plurality of projections is in contact with an uncured region in the sealant formed over the first substrate.
