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： To provide a plasma display panel and a field emission display having an anti-reflection function which can further reduce reflection of incident light from an external source. By providing an anti-reflection layer which geometrically includes a plurality of adjacent hexagonal pyramid-shaped projections, reflection of light is prevented. The reflective index changes from a surface side of display screen to an out side (an atmosphere side) due to a physical shape of a hexagonal pyramid. The plurality of hexagonal pyramid-shaped projections can be provided densely without any space remaining, and six surfaces of side of the hexagonal pyramid-shaped projection are each provided at different angles to a base surface. Therefore, light ray can be effectively scattered in many directions.

摘要： An anti-reflection film that can provide high visibility and has an anti-reflection function by which reflection of incident light from external can be further reduced, and a display device having such an anti-reflection film. A plurality of contiguous pyramidal projections is arranged in a geometric pattern, so that reflection of incident light is prevented. In addition, a protective layer formed of a material having a lower refractive index than the pyramidal projections is provided so as to fill a space between the plurality of pyramidal projections. The plurality of pyramidal projections has a hexagonal shape and can be densely arranged with no space therebetween. Further, since six sides of each pyramidal projection are provided at a different angle from the base, light can be effectively scattered in many directions.

摘要： It is an object of the present invention to provide a PDP and an FED with excellent visibility and a high level of reliability that each have an antireflective function by which reflection of external light can be reduced. A plurality of adjacent pyramidal-shaped projections and an antireflective layer equipped with a covering film that covers the projections are provided. The reflection of light is prevented by the index of refraction of incident light from external being changed by a pyramid, which is a physical shape, projecting out toward an external side (atmosphere side) of a substrate that is to be used as a display screen as well as by the covering film used to cover the projections being formed of a material that has a higher index of refraction than the index of refraction of the pyramidal projection.

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.
