Abstract
Disclosed is a display unit employing an organic electroluminescence element of an active matrix system, which has high picture quality and requires a low fabrication cost. The display unit comprises an organic electroluminescence element (14) and a bipolar transistor (11) stacked on the organic electroluminescence element (14). The organic electroluminescence element (14) comprises a hole transport layer (4), a luminescent layer (5) and an electron transport layer (6). The bipolar transistor (11) comprises a collector region layer (6), a base region layer (7) and an emitter region layer (8). The collector region layer (6) of the bipolar transistor (11) and the electron transport layer (6) of the organic electroluminescence element (14) are formed by a common single layer.
