Abstract
Abstract A panel with an anti-reflective multi-layered film thereon comprises a glass substrate, an electricity collector for leading static electricity which is formed by baking an electric conductive frit paste on the glass substrate, and has a rough surface, an anti-reflective multi-layered film formed on the glass substrate so as to cover at least a portion of the electricity collector and wherein the film includes an inner electric conductive layer to provide antistatic effect, wherein the thickness of the anti-reflective multi-layered film is less than the maximum height of the surface roughness of the electricity collector, and a lead terminal for earth provided on the outermost layer of the anti-reflective film and above the electricity collector, whereby static electricity produced on the glass substrate with the anti-reflective multi-layered film is collected at the electricity collector through the electric conductive layer so that the static electricity is led to the outside through the lead terminal for earth via the electricity collector.
