We describe a lighting tile having a substrate bearing an electrode structure, the electrode structure comprising: a plurality of electrically conductive tracks disposed over said substrate; and an electrical connection region connecting to said plurality of tracks; wherein the height of said tracks tapers away from said connection region to compensate for a reduction in luminance from said lighting tile array from the electrical connection region which arises from a non-uniform voltage drop which appears along the tracks in use. Advantageously the tracks are fabricated by electroplating: then, as the rate of deposition is determined by the voltage drop along a track during plating, the height of the deposited tracks, and therefore their resistance, will match the profile required in operation to compensate for the reduction in luminance which would otherwise occur.
