Patent ID: 8013534

Claim:
An electro-optic device comprising: a substrate on which a plurality of electro-optic elements are configured; a plurality of integrated circuit chips that drive the plurality of electro-optic elements, each of the plurality of integrated circuit chips including a first power terminal and a second power terminal connected to each other in the integrated circuit chip, a third power terminal sandwiching the first power terminal with the second power terminal and placed on a first side opposite to the second power terminal, and a fourth power terminal sandwiching the second power terminal with the first power terminal and placed on a second side opposite to the first power terminal; and a plurality of wiring patterns including a first power trunk line connecting the second power terminal in a first integrated circuit chip among from the plurality of integrated circuit chips and the first power terminal in a second integrated circuit chip placed on the second side of the first integrated circuit chip, a second power trunk line connecting the fourth power terminal in the first integrated circuit chip and the third power terminal in the second integrated circuit chip, a first electric supply line that supplies a first potential for driving the electro-optic elements from a power supply circuit to the first power terminal in the first integrated circuit chip, and a second electric supply line that supplies a second potential for driving the electro-optic elements from the power supply circuit to the third power terminal in the first integrated circuit chip.
