摘要： An array substrate and a display device. The array substrate (100) includes a base substrate (110), a first electrode (120), a first insulating layer (130) and a second electrode (140). The first electrode (120) is on the base substrate (110); the first insulating layer (130) is on a side of the first electrode (120) away from the base substrate (110); the second electrode (140) is on a side of the first insulating layer (130) away from the first electrode (120). The second electrode (140) is provided with a first through-hole (141) and a slit (142) communicated with the first through-hole (141) and extending from the first through-hole (141) to an edge of the second electrode (140), and an orthographic projection of the first electrode (120) on the base substrate (110) completely falls within an orthographic projection of the second electrode (140), the first through-hole (141) and the slit (142) on the base substrate (110). At this time, the first electrode (120), the second electrode (140), and the first insulating layer (130) can constitute a capacitor (Cst). The array substrate can ensure that the actual capacitance value of the capacitor is consistent with the design value when the alignment deviation occurs, thereby improving the yield of the display device using the array substrate.
