NOVELTY - A transparent substrate comprises invisible electrodes including a transparent support having transparent conductive film. The electrodes and their contact zones are structured with contours separated by non-conductive spaces, where the conductive film located at the site of the non-conductive spaces includes nano fissures.    USE - Used as e.g. a touch-type control screen for an electronic apparatus or a closing plate for a liquid crystal display cell or a photovoltaic cell for an electronic apparatus (claimed).    ADVANTAGE - Improved qualities of transparency and uniformity.    DETAILED DESCRIPTION - A transparent substrate comprises invisible electrodes including a transparent support having transparent conductive film, where electrodes and their contact zones are structured with contours separated by non-conductive spaces, where the conductive film located at the site of the non-conductive spaces includes nano fissures for interrupting the electrical conductivity between neighboring electrodes, without altering the path of a light ray in a manner perceptible to the naked eye.    An INDEPENDENT CLAIM is also included for a method of manufacturing a transparent substrate, comprising:    (1) placing the substrate, formed of the support and the conductive film possibly deposited on an intermediate layer made of a transparent hard non-conductive material, in a sealed enclosed space having a gaseous fluid supply inlet and a pump outlet;    (2) inserting, between the UV radiation source and the substrate, a mask including windows transparent to UV radiation, the windows corresponding to the dielectric non-conductors; and    (3) adjusting, as a function of the choice of materials used for the substrate and the emitting source, the UV radiation features to cause nano fissures to be created in the conductive film in the radiated zone, without removing any matter.    DESCRIPTION OF DRAWING(S) - The figure shows a device for obtaining the transparent substrate.    Transparent conductive oxide (5)    Window (8)    Mask (10)    Convex lens (16)    Diverging lens (18)
