Array substrate and display panel

An array substrate, comprising a base substrate and at least one signal line unit on the base substrate, the array substrate comprising a fan-out region, and the at least one signal line unit being in the fan-out region, wherein

• each of the at least one signal line unit comprises two first signal lines and one second signal line;
• in each of the at least one signal line unit, the two first signal lines are in a same layer and extend along a same direction, and the one first signal line and the two second signal lines are in different layers and are insulated from each other;
• and
• a center line of an orthographic projection of the one second signal line on the base substrate along an extending direction of the one second signal line overlaps with a center line of an orthographic projection of an interval region between the two first signal lines along an extending direction of the two first signal lines.
