PROBLEM TO BE SOLVED: To suppress increase in an area due to a power supply line and to obtain a small-size device in a semiconductor device having a power supply circuit laid on an array substrate. SOLUTION: The power supply circuit 5 is laid adjacent to a power supply voltage input terminal 6a and a signal line driving circuit 3. A large current passes in the power supply line 8 between the power supply circuit 5 and the power supply voltage input terminal 6a and in the power supply line 9 between the power supply circuit 5 and the signal line driving circuit 3. Therefore, by laying the power supply circuit 5 adjacent to the power supply voltage input terminal 6a and the signal line driving circuit 3, the length of the power supply lines 8, 9 is decreased. Since this reduces the line resistance which is proportional to the product of the length and the width, it is allowable to form thin power supply lines 8, 9. The wiring area can be reduced because the power supply lines 8, 9 can be made short and thin. COPYRIGHT: (C)2005,JPO&NCIPI |
