Abstract
A display driver includes amplifier circuits, D/A conversion circuits configured to output D/A conversion voltages to the amplifier circuits, a logic circuit, and signal line groups that couple the D/A conversion circuits to the logic circuit. The amplifier circuits are disposed in a direction D. The D/A conversion circuits are disposed in the direction Don a direction Dof the amplifier circuits. The logic circuit is disposed on the direction Dof the D/A conversion circuits, and outputs first to n-th display data, with each display data being k bits, to the D/A conversion circuit on the signal line group in a time division manner.
