<p><P>PROBLEM TO BE SOLVED: To provide a line head whose emission luminance is made uniform. <P>SOLUTION: Blocks B1 to B39 are provided with 89 pixel circuits P1 to P89, and a block B40 is provided with 73 pixel circuits P1 to P73. As distances from supply terminals Ta and Tb are made longer, a power supply impedance is increased. A load is reduced because the pixel circuits are set so that the number of the pixel circuits P1 to P73 included in the block B40 farthest from the supply terminals Ta and Tb. As a result, power supply variation of power supply lines La and Lb is suppressed. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
