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： 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： An object of the invention is to provide a display device having a high contrast ratio. Another object of the invention is to manufacture such a high-performance display device at low cost. In a display device having a display element between a pair of light-transmissive substrates, polarizer-including layers, which have different wavelength distributions of extinction coefficients, are stacked so that absorption axes are in a parallel nicol state, over each light-transmissive substrate. Absorption axes of one of a pair of stacks of polarizers and the other together which interpose the display element are deviated from a cross nicol state. A retardation plate may be provided between the stack of polarizing plates and the substrate.
