<P>PROBLEM TO BE SOLVED: To suppress lack of power supply ability, which occurs in one of two power supply lines for supplying mutually different power source potentials. <P>SOLUTION: An image display device includes: a plurality of data lines; a plurality of switch control lines crossing the data lines respectively; and a vertical scanning circuit including two power supply lines and a plurality of switch control signal supply circuits each of which outputs a potential to one of the plurality of switch control lines. The two power supply lines supply two kinds of mutually different power source potentials. Each switch control signal supply circuit selectively outputs a potential corresponding to one of the two kinds of power source potentials at the timing of supply of data signals to the plurality of data lines. A width of the power supply line for supplying a power source potential corresponding to a potential which major switch control signal supply circuits output at this timing, out of the two kinds of power source potentials is thicker than that of the power supply line for supplying the other power source potential. <P>COPYRIGHT: (C)2012,JPO&INPIT |
