Abstract:
A display device for performing a display operation, comprising:an addressing element including an organic electric luminescent element having a plurality of areas arranged in a matrix for emitting signal light, a plurality of first striped electrodes facing one surface of said organic electric luminescent element and extending in a predetermined direction, and a plurality of second striped electrodes facing another surface of said organic electric luminescent element and extending in a direction perpendicular to said first striped electrodes, said second striped electrodes being transparent with respect to the signal light;a display element including a light-receiving element for receiving the signal light and generating carriers corresponding to the signal light, an organic electric luminescent layer adjacent to said light-receiving element, a plurality of first display electrodes each facing one surface of said light-receiving element, and a second display electrode facing one surface of said organic electric luminescent layer; anda half mirror interposed between said addressing element and said light-receiving element and set so that a distance L to said first striped electrodes and a wavelength .lambda. of the signal light substantially satisfy L=n.multidot..lambda./2, where n is a natural number;wherein said organic electric luminescent layer of said display element emits display light when the carriers generated by said light-receiving element are recombined in said organic electric luminescent layer responsive to a voltage applied between said first display electrodes and said second display electrode.
