The invention relates to the technical field of display, in particular to an array substrate, a display panel and a display device, which can reduce the occurrence of electric leakage of transistors in the array substrate and improve the display picture quality of the display panel. The array substrate comprises a plurality of pixel driving circuits, and each pixel driving circuit at least comprises a compensation transistor. Wherein the active layer arranged on one side of the substrate comprises an active layer pattern of the compensation transistor, and the active layer pattern of the compensation transistor comprises two channel regions and a conductive region connected between the two channel regions. The first gate layer arranged on the side, away from the substrate, of the active layer comprises a first gate signal line, and the orthographic projection of the first gate signal line and the orthographic projection of the two channel regions on the substrate are overlapped. The second gate layer arranged on the side, away from the substrate, of the first gate layer comprises a voltage stabilizing pattern, the voltage stabilizing pattern is configured to receive a power supply voltage signal, and the orthographic projection of the voltage stabilizing pattern and the orthographic projection of the conductive area on the substrate are overlapped.
Description
technical field [0001] The present invention relates to the field of display technology, and in particular, to an array substrate, a display panel and a display device. Background technique [0002] The display panel includes pixels arranged in an array, and each pixel includes a pixel driving circuit and a light emitting device that are electrically connected. The pixel driving circuit controls the light-emitting brightness and light-emitting time of the light-emitting device by controlling the turn-on and turn-off of its internal transistors. The connection points between the transistors and the lines inside the pixel driving circuit are easily affected by other electromagnetic signals, causing voltage shifts at the transistors or the connection points, resulting in leakage. SUMMARY OF THE INVENTION [0003] In order to overcome the above-mentioned defects in the prior art, the present invention provides an array substrate, a display panel and a display device, which ca...
