Abstract
The invention relates to a transparent display material having a conducting layer of a tin oxide and/or indium oxide composition which withstands electrochemical attacks without the need for elaborate measures. To this end, the invention provides that the conducting layer contains at least one metal of the Ib and/or eighth transition metal group with a content of from about 10-3 to 3% by weight, relative to tin oxide and/or indium oxide. The conducting layer according to the invention is particularly well suited for use in liquid-crystal displays.
