Abstract
Metal-oxide layers having a high .delta..sub.max, such as in particular magnesium-oxide layers, are provided on a glass substrate, such as a selection plate or a channel plate, of an electronic display device by means of a spray-pyrolysis process. To this end, a solution of a metal salt, such as Mg acetate, in ethanol or another (organic) solvent and/or water is sprayed onto a substrate which is maintained at a temperature of 350-550.degree. C. In a display device which is provided with such a layer on the bottoms and walls of the channels of the channel plate, a minimum transport voltage of 50-100V/cm is required.
