Abstract

The present disclosure relates to a display panel and a display device. A source driving unit and a gate driving unit in the display panel are arranged in a peripheral area on two opposite sides of a display area respectively, namely when the source driving unit and the gate driving unit are longitudinally arranged in the peripheral area at the upper end and the lower end of the display area respectively, narrow-bezel design on the left side and the right side of the display panel can be achieved, and when the source driving unit and the gate driving unit are transversely arranged in the peripheral area at the left end and the right end of the display area respectively, narrow-bezel design on the upper side and the lower side of the display panel can be achieved. Therefore, compared with the mode that a plurality of display panels are connected to achieve multi-screen display in the prior art, the narrow-bezel design on the left side and the right side of or the upper side and the lower side of the display panel provided by embodiments of the present disclosure can be achieved, so that when transverse or longitudinal multi-screen display is achieved, a non-image-display area at the connecting position of adjacent display panels is relatively small, thereby the visual effect of a display image is effectively improved.
