Abstract
A touch electrode structure, a touch panel and a display device are provided. The touch electrode structure includes at least one first touch electrode (101) and a plurality of second touch electrodes (102), the at least one first touch electrode is of annular shape; the plurality of second touch electrodes (102) are insulated from the at least one first touch electrode (101), the plurality of second touch electrodes (102) are arranged along a circumferential direction of the annular first touch electrode (101) and extend along a radial direction of the annular first touch electrode (101), so as to overlap the at least one first touch electrode (101). The touch electrode structure may be used in a non-rectangular touch panel, which can solve a problem that an edge of the touch panel or the touch electrode at the corner is not completely or evenly covered.
