<P>PROBLEM TO BE SOLVED: To improve luminance unevenness of an image display device equipped with organic light emitting diodes. <P>SOLUTION: A plurality of pixel circuits 400 are arrayed in a pixel region A. Main power lines LR, LG, and LB are provided outside the pixel region A. Further, 1st subordinate power lines Lr1, Lg1, and Lb1 and 2nd subordinate power lines Lr2, Lg2, and Lb2 are provided in the pixel region A, and those subordinate power lines are connected through a subordinate power source connection point P. The pixel circuit 400 is connected to the 1st subordinate power lines Lr1, Lg1, and Lb1 at a pixel connection point Q. Thus, the power wires are formed in a mesh shape to greatly reduce a voltage drop, thereby improving luminance unevenness. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
