Embodiment of the present application discloses an array substrate and a display panel. An active layer includes a first connection segment, a second connection segment, and a third connection segment connected in sequence. A part of the second connection segment of the active layer overlaps with a data line, and another part of the second connection segment locates between two adjacent data lines. The third connection segment locates between the two adjacent data lines. A drain electrode contacts a part of the active layer exposed between the two adjacent data lines.
