The present invention discloses an array substrate and a display panel. The array substrate includes an underlay substrate, scan lines disposed transversely, data lines disposed longitudinally, and a plurality of pixel units. Each pixel unit has a primary region and a secondary region. The pixel unit has a primary pixel electrode in the primary region and a secondary pixel electrode in the secondary region. The primary pixel electrode and the secondary pixel electrode are disposed at an interval, and the secondary pixel electrode surrounds a portion of the primary pixel electrode near the data lines.
