The invention relates to an electroluminescent display comprising a first display pixel and a second display pixel formed on a substrate. The display pixels comprise a first electrode deposited on or across the substrate, an electroluminescent layer and a second reflective electrode. The first and second display pixels are separated by a region comprising at least one insulating structure. The insulating structure is adapted to suppress the output of light at the second display pixel reflected at the second reflective electrode, which light is incident from at least the first display pixel and/or the substrate. The insulating structure reduces crosstalk of light between the first and second or further display pixel and can be easily integrated in the manufacturing process of the electroluminescent display.
