<P>PROBLEM TO BE SOLVED: To provide an image display device where the number of power supply wirings is reduced. <P>SOLUTION: The image display device includes a pixel array unit 1, a scanner unit and a signal unit. The pixel array unit 1 comprises first scanning lines WS, second scanning lines AZ1, third scanning lines AZ2 and fourth scanning lines DS arranged in rows; signal lines SL arranged in columns; pixel circuits 2 in a matrix, connected to the scanning lines and signal lines; and a plurality of power supply lines to supply a first potential Vss1, a second potential Vss2 and a third potential Vcc necessary for the operation of each pixel circuit 2. One scanning line in the first scanning line WS, the second scanning line AZ1, the third scanning line AZ2 and the fourth scanning line DS is used in common as one power supply line in a plurality of power supply lines to supply the first potential Vss1, the second potential Vss2 and the third potential Vcc necessary for the operation of the pixel circuit 2. <P>COPYRIGHT: (C)2008,JPO&INPIT |
