An array substrate, a display and an electronic device are disclosed. The array substrate includes a common electrode layer and a pixel electrode layer arranged opposite to each other, multiple switch elements, multiple data lines extending in a column direction, multiple common wires connected to the common electrode blocks respectively. The pixel electrode layer includes multiple pixel electrodes, and the common electrode layer includes multiple common electrode blocks. A pixel gap exists between adjacent columns of the pixel electrodes. The projections of the common wires on the pixel electrode layer are in separate pixel gaps from the projections of the data lines on the pixel electrode layer in the direction perpendicular to the pixel electrode layer. Two data lines having the projections in the same pixel gap are in separate layers.
