1. An extended film display, comprising a flexible film having two opposing sides; a pair of crossed electrodes, one on each different ones of said opposing sides of said film; a number of light-emitting elements dispersed in said film, said elements extending from one side of said film to the other, said elements being sandwiched between a crossover between said crossed electrodes and being sufficiently small to permit numbers of said elements to exist at said crossover, whereby activation of said electrodes at said crossover activates numbers of said elements therebetween; and means including said crossed electrodes for selectively activating said elements.
