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.

Abstract: A method for preparing matted display electrodes is provided. The electrodes are initially chemically treated in a solution to form a compound on said electrodes which is insoluable in said solution. Finally, the electrodes treated in a second solution which dissolves said compound.
