ABSTRACT A matt display electrode in a display device is formed by a chemical treatment of which a first step comprises forming a compound of the surface of the electrode and a second step of removing the compound. In the case of an aluminium electrode the compound is a layer of aluminium oxide-hydroxide. The highly roughened surface resulting from removal or this compound provides excellent scattering of incident light.
