Scanning circuit and image display device

A scanning circuit which sequentially applies a scanning signal to a plurality of scanning wiring lines of a display device having the plurality of scanning wiring lines and a plurality of modulation wiring lines, said scanning circuit comprising:

• a plurality of output circuits each of which outputs the scanning signal to a respective one of the plurality of scanning wiring lines;
• a selecting circuit which outputs a selection signal for selecting the scanning wiring lines to which the scanning signal should be applied;
• a compensation signal output circuit which outputs a compensation signal for compensating for a loss in the scanning signal in;
• and
• a plurality of switches connected in common to said compensation signal output circuit, wherein an output from a said output circuit is supplied to said compensation signal output circuit through any of said plurality of switches, and wherein the output circuits which output the scanning signals are compensated on the basis of the compensation signal.
