Patent ID: 8269696

Claim:
A power supply line drive apparatus, wherein in a layout pattern of the power supply line drive apparatus: a drive power supply line is directly connected to a first source/drain of an n-channel MOS transistor and a first source/drain of a p-channel MOS transistor, a row of pixel circuits being directly connected to said drive power supply line; a different drive power supply line is directly connected to a first source/drain of a different n-channel MOS transistor and a first source/drain of a different p-channel MOS transistor, a different row of pixel circuits being directly connected to said different drive power supply line; a high-potential power supply line directly connects a second source/drain region of the n-channel MOS transistor to a second source/drain region of the different n-channel MOS transistor, said high-potential power supply line not crossing said drive power supply line or said different power supply line; a low-potential power supply line directly connects a second source/drain region of the p-channel MOS transistor to a second source/drain region of the different p-channel MOS transistor.
