Pixel array substrate

A pixel array substrate, comprising:

• a display area having a plurality of pixel areas therein;
• a plurality of signal lines and a plurality of transmission lines intersecting with each other to form the pixel areas;
• a plurality of selection lines passing the pixel areas, intersecting with the signal lines to form a plurality of intersection regions, and having a plurality of first contacts, a plurality of second contacts adjacent to the first contacts, and a plurality of third contacts adjacent to the first contacts, wherein the first contacts are respectively located on the intersection regions, and each of the first contacts is between one of the second contacts and one of the third contacts, and a first portion of the first contacts are passed by a line of the display area;
• and
• a plurality of jumper wires respectively passing the first contacts, wherein two ends of each of the jumper wires are respectively located on one of the second contacts and one of the third contacts, and a first portion of the jumper wires electrically connect the first portion of the first contacts and the second contacts that are adjacent to the first portion of the first contacts, but electrically isolate the third contacts that are adjacent to the first portion of the first contacts.
