ABSTRACT:
The currents that m pieces of quasi control current output circuits formed with a polycrystalline TFT output have the dispersion. In the present invention, the averaged value of the output currents of these m pieces of the quasi control current output circuits is outputted from the output terminals of n (n represents a natural number of m or less) of the control current output circuit. For example, the output currents of these m pieces of the quasi control current output circuits are in turn exchanged and outputted from the n (n represents a natural number of m or less) pieces of the output terminals of the control current output circuits. Thus, the drive circuit, which has suppressed the dispersion of the output current, can be provided.
