ABSTRACT:
The present invention reduces the power consumption of an organic electroluminescent display device. An organic electroluminescent display device can include organic electroluminescent elements corresponding to R, G, and B colors, holding capacitance, etc., which are disposed at intersections of data lines and scan lines which are arranged in a matrix manner. The display device can further include, a data line driving circuit, and a scan line driving circuit. The scan line driving circuit can include a decoder. An auxiliary data line driving circuit can also be provided in addition to the data line driving circuit. The auxiliary data line driving circuit includes a decoder, and a plurality of switching elements. First ends of the switching elements are selectively connected to only selected data lines of the data lines which correspond to the organic electroluminescent elements capable of emitting green (G). Second ends of the switching elements are connected to a power supply line on which a character display voltage VCHR for causing the organic electroluminescent elements to emit light can be fed.
