Abstract

Embodiments of the present disclosure provide an array substrate, a display panel and a display device, which may simplify bezels at three sides of the display panel and achieve the effect of almost zero bezel visually. Because a GOA design is not adopted, the cost of a drive circuit may be reduced, and poor relevant reliability caused by the GOA may be avoided. The array substrate comprises a display area and a drive circuit area. The display area includes: a plurality of pixel units, a plurality of data lines, and a plurality of gate lines. The drive circuit area includes: a drive module being configured to provide signals to data lines and gate lines. The drive circuit area is outside of the display area and close to the data lines. The embodiments of the present disclosure are used to manufacture the array substrate, the display panel and the display device.
