An electroluminescent display comprising a mask defining the information to be displayed and an electroluminescent (EL) backlight. The mask compress a layer (13) of physically-stabilised liquid crystal switchable to define the information to be displayed mounted in front of an EL layer (16) of the backlight. At least one pair of electrodes (12, 20) are arranged to generate, in use, an electric field across both the EL layer (16) and the LC layer (13). A barrier layer (15) is provided between the LC layer (13) and the EL layer (16) that restricts migration of liquid crystal from the LC layer (13) to the EL layer (16).
