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： To improve the response speed of liquid crystal molecules when a liquid crystal display device is changed from an on state to an off state. A liquid crystal display device that includes a liquid crystal material between a substrate and a counter substrate; a plurality of pixels over the substrate; and a microstructure which is provided over the substrate, is in contact with the liquid crystal material, and includes a movable portion and a method for manufacturing the liquid crystal display device are provided. The microstructure may include a lower electrode, an upper electrode, and a space between the lower electrode and the upper electrode. The microstructure is manufactured through the steps of forming the lower electrode over the substrate, forming a sacrificial layer over the lower electrode, forming the upper electrode over the sacrificial layer, and removing the sacrificial layer by etching to form the space.

摘要： An object is to provide a display device with high contrast ratio. Another object is to manufacture such a high-performance display device at low cost. 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.

摘要： The present invention provides a display device with higher contrast ratio. The display device includes a first substrate, a second substrate, a layer including a display element which is interposed between the first substrate and the second substrate, and stacked polarizers on an outer side of the first substrate or the second substrate. The stacked polarizers are arranged to be in parallel Nicols. The stacked polarizers have the same wavelength distribution in the extinction coefficients. Further, a retardation plate may be provided between the stacked polarizers and the first substrate or the second substrate. The stacked polarizers are provided for both of the first substrate and the second substrate, and the stacked polarizers on the outer side of the first substrate and the stacked polarizers on the outer side of the second substrate are arranged to be in crossed Nicols or parallel Nicols.
