Abstract
The evenness of the brightness of a display apparatus is enhanced. A drive control signal generation circuit supplies drive control signals to drive circuits, respectively. Drive power source input pads are connected to each other by a drive power source line in a chip, and provided with potentials from the same power source outside the chip. The drive circuits respectively comprise drive circuit input terminals which are connected at predetermined intervals to the drive power source line. Under the control of the drive control signals, the drive circuits transmit potentials received at the drive circuit input terminals to drive signal output pads, respectively. A difference in drive output impedance between the drive signal output pads is thereby suppressed.
