<P>PROBLEM TO BE SOLVED: To solve a problem with a conventional wiring pattern where there is high possibility of an inter-layer short circuit due to dust or the like between a driving power feed line to which high voltage is applied and a high potential power feed line. <P>SOLUTION: In a display panel in which the light emission state and the non-light emission state of a pixel circuit are controlled in row units by two kinds, high potential and low potential of power supply potentials, a power feed line driving circuit, a high potential power feed line and a low potential power feed line are disposed. The power feed line driving circuit supplies either high potential power supply potential or low potential power supply potential to the corresponding driving power feed line based on the power line driving pulse. The high potential power feed line is wired in a position not intersecting the driving power feed line, and the lower potential power feed line supplies low potential power supply potential to the power feed line driving circuit. <P>COPYRIGHT: (C)2009,JPO&INPIT |
