An electroluminescent device which includes a close arrangement including a first set of fibers and a second set of fibers being arranged to form a two dimensional close array of junctions between fibers of the first set of fibers and fibers of the second set of fibers, wherein each of the fibers includes a longitudinal conductive element, whereas fibers of at least one of the first and second sets of fibers further include a longitudinal coat of at least one light emitting substance being in intimate contact with the conductive element, the at least one light emitting substance is selected such that on applying an electric field between crossing conductive elements, radiation is emitted from the light emitting substance.
