PROBLEM TO BE SOLVED: To manufacture an EL element capable of effectively utilizing the light from a light emitting material by successively providing a light guide, a light transmissive rear electrode and a rear seal material in conformity with a protruding part formed of a part of the spherical surface of a plurality of minute lens groups regularly arranged on the surface. SOLUTION: In conformity with a protruding part formed of a part of the spherical surface of a plurality of fine lens groups 1 regularly arranged on the surface, a light guide 2 having a conical hole in recessed form is provided on the reverse side, and a light transmissive rear electrode and a rear seal material 6 are successively provided through a light transmissive front electrode 3 and a light emitting material 4. When an ac voltage is applied between the light transmissive front electrode 3 and the light reflecting plate-and-rear electrode to emit a light from the light emitting material 4 in such a structure, the emitted light is transmitted by the light transmissive front electrode 3 and guided to the front surface with respect to the electrode vertical surface. The light emitted horizontally to the electrode surface and the light reflected by the light reflecting plate-and-rear electrode are guided to the front surface through the light guide 2. |
