Abstract: The disclosure discloses a display panel, a manufacturing method thereof and a display device. The display panel includes a backing substrate, a first active layer arranged over the backing substrate, and a second active layer arranged on a side of the first active layer away from the backing substrate. The first active layer and the second active layer each comprise a conductor region, and perpendicular projections of the conductor regions of the first and second active layers on the backing substrate have an overlapping region. A part of the conductor region of the first active layer corresponding to the overlapping region forms as a first electrode, a part of the conductor region of the second active layer corresponding to the overlapping region forms a second electrode, and the first electrode and the second electrode form two electrodes of a capacitor.

Abstract: The disclosure provides a display panel, an array substrate and a fabrication method thereof. The fabrication method of the array substrate includes forming a plurality of first thin film transistors and a plurality of second thin film transistors on the first substrate. The etch stopper layer of the second thin film transistor is different from an etch stopper layer of the first thin film transistor, and a threshold voltage of the second thin film transistor is higher than a threshold voltage of the first thin film transistor. By using the disclosed thin film transistors to form the gate driving circuit, the second thin film transistor with a high threshold voltage can be used as the driving signal outputting transistor. The abnormal multi-pulse of the gate driving circuit and the display panel caused by the low threshold voltage of the second thin film transistors may be therefore avoided.

Abstract: A display panel and a display device are disclosed. Each of pixels in the display panel includes a pixel area; a switch element located near an intersection of a data line and a scan line; a pixel electrode electrically connected to the switch element; and a common electrode located on the first substrate. The common electrode comprises first common electrodes superposing data lines or scan lines and having the same first width; and second common electrodes overlapping with respective pixel areas and having the same second width, the first width is the same as the second width. Alternatively, the common electrode comprises first slits, which have the same first slit width, located above data lines and scan lines, and second slits, which have the same second slit width and are located in respective pixel areas. The first slit width is the same as the second slit width.
