Abstract: The present disclosure provides a driving circuit of a display panel and a display device. The driving circuit includes a gate-on-array (GOA) circuit transmitting a scan driving signal to the display panel through a corresponding gate signal line, and further includes a pull-down module and a control bus. The pull-down module is activated at a falling edge of a gate driving signal to accelerate a potential descent speed of the pull-down module, thereby increasing a charging time of a thin film transistor and realizing a narrow-frame display panel.

Abstract: Embodiments of this application disclose a display panel. A primary pixel electrode is disposed inside a primary pixel region, and a sub-pixel electrode is disposed inside a sub-pixel region. First shading strips and second shading strips are intersected to form a plurality of primary frame bodies. One primary frame body correspondingly encloses a circumferential side of one pixel region. A third shading strip is disposed inside the primary frame body and correspondingly disposed between the primary pixel region and the sub-pixel region. The third shading strip and the primary frame body define two sub-frame bodies, and a channel for making the two sub-frame bodies communicate is disposed on the third shading strip.
