Touch array substrate, display panel and display device

A touch array substrate, comprising:

• a plurality of first electrodes, disposed in a row direction and a column direction to form a plurality of electrode rows and a plurality of electrode columns;
• and
• a plurality of sub pixels, disposed in the row direction and the column direction to form a plurality of pixel rows and a plurality of pixel columns;
• wherein an edge of the plurality of first electrodes in the column direction comprises a convex shape and a concave shape, the convex shape of an edge of one of two adjacent ones of the plurality of electrode columns extends into the concave shape of an edge of the other of the two adjacent ones of the plurality of electrode columns,
• the plurality of sub pixels comprise a plurality of gap sub pixels, each of the plurality of gap sub pixels is partially overlapped with each of the two adjacent ones of the plurality of electrode columns, and the gap sub pixels corresponding to the two adjacent ones of the plurality of electrode columns are located in different pixel columns.
