摘要： It is an object to provide a display device having an electroluminescent element in which a contrast ratio is increased. In a display device having an electroluminescent element between a pair of light transmitting substrates, a circularly polarizing plate having stacked polarizing plates arranged on outer sides thereof is provided. At this time, opposed polarizing plates are arranged to be in a crossed nicol state or in a parallel nicol state. As a result, a display device with a high contrast ratio can be provided.

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.

摘要： The display device includes an anti-reflection film having a plurality of projections over a display screen surface and a protective layer filling a space between the projections. The number of times of incidence of external light entering the display device on the anti-reflection film is increased; therefore, the amount of external light transmitted through the anti-reflection film is increased. Thus, the amount of external light reflected to a viewer side is reduced, and the cause of a reduction in visibility such as reflection can be eliminated. Further, since the plurality of projections is covered with a protective layer, entry of dust can be prevented, and physical strength of the anti-reflection film can be increased.
