摘要： The invention provides a display device of which a contrast ratio is enhanced. By providing stacked polarizing plates so as to be in a cross nicol state, a contrast ratio of a display device can be enhanced. The stacked polarizing plates are stacked outside a light-transmissive insulating substrate in a parallel nicol state. When the number of polarizing plates is four or five in total, a contrast ratio becomes the highest.

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.

摘要： There is disclosed a lightweight and small liquid crystal display which achieves low power consumption and in which the optical anisotropy of the liquid crystal material is compensated for in order to enhance the viewing angle characteristics and the response speed of the liquid crystal material. Display electrodes and a common electrode are formed on one of the substrates. The orientation of the liquid crystal material is of the HAN (hybrid alignment nematic) type. This compensates for the optical anisotropy of the liquid crystal material and improves the response speed.
