Pixel array substrate and display panel

A display panel comprising:

• a pixel array substrate, comprising:
• a substrate comprising a display region and a periphery circuit region substantially connected to the display region;
• a plurality of pixel structures arranged in array in the display region;
• a plurality of signal lines disposed in the display region and formed in a first conducting wire layer, and respectively electrically connected to the pixel structures;
• a plurality of first traces disposed in the periphery circuit region and formed in a second conducting wire layer;
• a plurality of second traces disposed in the periphery circuit region and formed in the first conducting wire layer, the second traces being insulated from the first traces;
• a plurality of first conductive structures, a part of the signal lines respectively electrically connecting to the first traces by the first conductive structures;
• and
• a plurality of second conductive structures, another part of the signal lines respectively electrically connecting to the second traces by the second conductive structures;
• an opposite substrate opposed to the pixel array substrate;
• and
• a display medium disposed between the pixel array substrate and the opposite substrate.
