PROBLEM TO BE SOLVED: To provide a full-color organic EL display unit with which localized defective resistance and disconnection of a second electrode formed on an organic layer are eliminated. SOLUTION: A hole injection layer 40 and a hole transport layer 41 are formed on the surface of the first electrodes 2 and insulation layers 3 covering across a plurality of first electrodes 2. Fields for each color 60a, 60b, 60c are selected and luminous layers 42a, 42b, 42c, electron transport layers 43a, 43b, 43c, electron injection layers 44a, 44b, 44c are formed in each field. An organic layer composed of the hole injection layer, the hole transport layer, the luminous layer, the electron transport layer and of the electron injection layer forms a continuous layer connecting the fields 60a, 60b, 60c selected for each color. The thickness of the organic layer for each color is made different for the purpose of adjusting luminous efficiency, which forms unevenness on the surface of the organic layer. The layer thickness of a second electrode, however, is configured to be bigger than the maximum value of the addition of the thickness of the luminous layer and that of the electron transport layer.
