Abstract
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 SiO2 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.
Claims7
A conductive anti-reflection film, comprising:
- a first layer disposed on a surface of a substrate, said first layer containing first conductive particles;
- and
- a second layer disposed for covering said first layer, said second layer containing SiO2 and second conductive particles,
- wherein the content of the second conductive particles contained in said second layer is in the range from greater than 5 to 40 wt % to the total content of the second particles and SiO2.
A cathode ray tube, comprising:
- a face plate having a first surface containing a phosphor substance;
- a first layer disposed on a second surface opposite to the first surface of said face plate, said first layer containing first conductive particles;
- and
- a second layer disposed for covering said first layer, said second layer containing SiO2 and second conductive particles,
- wherein the content of the second conductive particles contained in said second layers is in the range from greater than 5 to 40 wt % to the content of the second particles and SiO2.
