Abstract

PURPOSE:To eliminate the nonlinearity caused by a single current enclosure structure in a double current contraction type light emitting diode by forming a current contraction portion for limiting a light emitting region in the upper and the lower directions of the light emitting layer. CONSTITUTION:Upper and lower current contraction diameters dw and de are formed equal. An electric current implanted to the upper current contraction portion 39 from a P-type side electrode 36 flows as it is toward an opposite electrode 40 directly thereunder, and even if the input current level is altered, no current path changes, and the light emitting diameter d does not accordingly vary. When the layer resistance of the P<+>-type diffused layer of the upper current contraction portion 39 is further formed sufficiently low, the current density in the light emitting region d becomes constant. Accordingly, the current density distribution does not become in disorder due to the variations in the input current level.
