A display unit has a face surface and a multi-layered antireflection antistatic film composed of three layers or more which are formed on the face surface. The multi-layered antireflection antistatic film has an absorption layer, a conductive layer, and a protect layer in the order from a face surface side. The absorption layer includes at least one kind of organic coloring matter, SiO , and a silane coupling agent, and the silane coupling agent content thereof is seven times or less by weight the total solid content of SiO and the organic coloring matter.

Display unit having antireflection antistatic film and manufacturing method thereof

A conductive anti-reflection film is disclosed, that comprises a first layer containing first conductive particles and a second layer disposed for covering the first layer, the second layer containing SiO and second conductive particles. A conductive anti-reflection film prevents the AEF (Alternating Electric Field) from taking place and light from reflecting and allows the front surface to be conductive. In addition, the conductive anti-reflection film has high productivity and high durability. A cathode ray tube displays a high quality picture for a long service life.

Conductive anti-reflection film and cathode ray tube

A second coat film is formed on a first coat film containing a conductive substance, the second coat film having an expansion coefficient almost the same as the expansion coefficient of the first coat film under a sintering condition. The first and second coat films are sintered at the same time. Thus, a conductive anti-reflection film with sufficiently low surface resistance, excellent water resistance and chemical resistance, and reduced reflected light can be obtained. When the conductive anti-reflection film is used, a cathode ray tube that is almost free from the AEF (Alternating Electric Field) and that displays a high quality picture for a long time can be obtained.

Method of fabricating conductive anti-reflection film for a cathode ray tube

A second film that contains a substance that secures the conductivity of conductive particles is formed on a first film that contains the conductive particles. The first film and the second film are sintered at the same time. Thus, a conductive anti-reflection film having a sufficiently low surface resistance with a sufficient transmissivity for a high transparency can be obtained with high cost performance. When the conductive anti-reflection film is used for a cathode ray tube, it can almost prevent the AEF (Alternating Electric Field), display a picture in high quality, and be excellent in cost performance.

Conductive anti-reflection film for cathode ray tube

The present invention is directed to an antireflection film having a multilayer structure in which an antireflection multi-layer film including at least two thin films is formed on a substrate, wherein at least one of the thin films contains a coloring agent. The antireflection multi-layer film absorbs light of an entire range of wavelength of 400-700 nm, and the reflectance of the antireflection multi-layer film with regard to the wavelength, light of which this antireflection multi-layer film can absorb, is smaller than the reflectance of the substrate. The antireflection film can be applied to a cathode ray tube or a light-transmitting display substrate of a display apparatus such as a liquid crystal display apparatus for the purpose of effectively avoiding reflection of external light.
