Abstract:
A display device comprising:a substrate having a surface side;first light emission elements which emit light in a predetermined range of wavelengths when a predetermined voltage is applied to said first light emission elements, said first light emission elements being arranged at the surface side of said substrate and each including an anode electrode, an organic electroluminescent layer and a cathode electrode;light waveguides, each of which guides the light emitted from a corresponding one of said first light emission elements;active elements, each having a first end and a second end and in each of which a carrier occurs upon incidence of the light emitted from a corresponding one of said first light emission elements and guided by a corresponding one of said light waveguides;data electrodes to which a voltage is applied in accordance with image data, the first end of each said active elements being connected to a corresponding one of said data electrodes; andsecond light emission elements which emit light in a predetermined wavelength range when currents flow in said second light emission elements, each of said second light emission elements being arranged at the surface side of said substrate and being connected to the second end of a corresponding one of said active elements, and each of said second light emission elements including an anode electrode, an organic electroluminescent layer and a cathode electrode which are formed of respective same materials as the anode electrode, the organic electroluminescent layer and the cathode electrode of each of said first light emission elements.
