A display unit has an interlayer formed at least as one or more than one layers and arranged between a light-emitting layer and a diffractive element. The interlayer has a thickness not less than 500 nm and not more than 2,000 nm and an average refractive index greater than a refractive index of the light-emitting layer. The optical path length of the interlayer defined as a product of multiplication of its average refractive index by its thickness satisfies the requirement shown below: ( m + 0.1 ) 2 · 1 - ( n L n m ) 2 ≤ n m ⅆ ≤ ( m + 0.6 ) · λ 0 2 · 1 - ( n L n m ) 2 where m is an integer not less than 0; λ0 is a wavelength in vacuum; nm is the average refractive index of the interlayer; d is the thickness of the interlayer; and nL is the refractive index of the light-emitting layer.

An image display device comprises an electromagnetic shielding film and a moire preventing film attached thereto. The electromagnetic shielding film has a conductive portion and an opening portion, and the moire preventing film has a moire preventing part. When the conductive portion and the opening portion form a mesh pattern, the moire preventing part may be formed approximately at the center of the opening portion, and may be formed on an intersection of the mesh pattern.

摘要:
A field emission display with reflection layer has an improved insulating supporting device. The major feature is to place a reflection layer on the insulating supporting device. From the special structure, the insulating supporting device can enhance the emission efficiency of the phosphors powder rather than the primary function of the insulating support. The field emission display with reflection layer has an anode structure, a cathode structure and the supporting device.
