Pixel array substrate

A pixel array substrate, comprising:

• a plurality of scanning line pads and a plurality of data line pads located on a substrate, wherein the scanning line pads and the data line pads are arranged in an arrangement direction;
• a plurality of scanning lines extending along a first direction;
• a plurality of data lines and a plurality of gate transmission lines extending along a second direction, wherein the scanning lines are electrically connected to the scanning line pads through the gate transmission lines, and the data lines are electrically connected to the data line pads;
• and
• a plurality of red sub-pixels, a plurality of green sub-pixels, and a plurality of blue sub-pixels electrically connected to the scanning lines and the data lines, wherein the data line pads comprises a plurality of first data line pads, a plurality of second data line pads, and a plurality of third data line pads, wherein the red sub-pixels are electrically connected to the first data lines pads, the green sub-pixels are electrically connected to the second data line pads, and the blue sub-pixels are electrically connected to the third data line pads, wherein a number of the scanning line pads located between the first data line pads and the second data line pads or between the third data line pads and the second data line pads in the arrangement direction is less than a number of the scanning line pads located between the first data line pads and the third data line pads.
