<P>PROBLEM TO BE SOLVED: To attain high definition of pixels by improving power supply wiring of an active matrix type display device. <P>SOLUTION: The display device has signal lines SL in columns, scanning lines WS in rows, pixels 2 arranged corresponding to where they cross each other, a first-class power supply wiring Vss supplying a driving current to the respective pixels 2, and a second-class power supply wiring Vss supplying a reference voltage needed for operations of the respective pixels 2. The first-class power supply wiring Vcc is arranged in parallel to the signal lines SL in columns and a first class power supply wiring part of one column supplies the driving current to pixels 2 of the corresponding column, and meanwhile, the second power supply wiring Vss is arranged in parallel to the scanning lines WS in rows and a second-class power supply wiring part Vss of one row supplies the reference voltage to pixels 2 of the corresponding row. <P>COPYRIGHT: (C)2008,JPO&INPIT |
