P1 and second source signal wire P2 are identical as the connection type of IC chip, in the first power signal line P1 and second source
The voltage value at the both ends of signal wire P2, power supply signal is substantially suitable, but the first power signal line P1 is in the part of rim area BA,
I.e. third line segment P13 is not connected to display pixel, so that the voltage value on the first power signal line P1 is greater than second source signal wire
Voltage value on P2, that is, the actual supply voltage value of display pixel SP of the two sides relief area NA is larger on second direction y.
And due on power signal line P the voltage value difference much larger than the voltage value of the data drive signal on data line D difference,
