In a current driving apparatus for driving a display panel, allocation of some of transistors used for constructing current sources is exchanged between first and second DA converter circuits. For example, a current source corresponding to the most significant bit of the first DA converter circuit is composed of transistors disposed on the first, third, fifth and seventh rows of a first transistor group and transistors disposed on the second, fourth, sixth and eighth rows of a second transistor group adjacent to the first transistor group. Similarly, a current source corresponding to the most significant bit of the second DA converter circuit is composed of transistors disposed on the second, fourth, sixth and eighth rows of the first transistor group and transistors disposed on the first, third, fifth and seventh rows of the second transistor group.
