Abstract: The present application relates to an array substrate and a display panel. In the present application, a first common line and a first sharing line are respectively disposed on two sides of a scan line, thereby preventing a situation in the prior art that the first sharing line penetrates a main pixel region and a sub-pixel region vertically, thereby improving an aperture ratio and a transmittance of the array substrate. The first common line, the first sharing line, and the scan line are disposed in a same layer, thereby further improving the transmittance of the array substrate.
