TOUCH SENSOR AND DISPLAY DEVICE

A touch sensor (01) and a display device (03). The touch sensor (01) comprises a first opening area (422), a second opening area (421), a plurality of first touch electrodes (11) and a plurality of second touch electrodes (12). The first opening area (422) and the second opening area (421) are arranged at intervals. The center (013) of the first opening area (422) does not coincide with the center (011) of the touch sensor (01), and the center (012) of the second opening area (421) does not coincide with the center (011) of the touch sensor (01). The plurality of first touch electrodes (11) each extend along a first direction (D1), and at least one of the plurality of first touch electrodes (11) comprises a plurality of first touch sub-electrodes (111) that are arranged side-by-side in the first direction (D1) and are electrically connected to one another. The plurality of second touch electrodes (12) each extend along a second direction (D2) that intersects the first direction (D1), and at least one of the plurality of second touch electrodes (12) comprises a plurality of second touch sub-electrodes (121) that are arranged side-by-side in the second direction (D2) and are electrically connected to one another. The plurality of first touch electrodes (11) are arranged in parallel along the second direction, and the plurality of second touch electrodes (12) are arranged in parallel along the first direction. The plurality of first touch sub-electrodes (111) and the plurality of second touch sub-electrodes (121) as a whole at least partially surround the first opening area (422) and the second opening area (421). At least one of the plurality of first touch electrodes (11) comprises a first transfer touch electrode (15). Each of a first group of second touch electrodes (12) of the plurality of second touch electrodes (12) comprises a second transfer touch electrode (16). At least a part of the first transfer touch electrode (15) is located between the first opening area (422) and the second opening area (421) and comprises a first transfer touch sub-electrode (151) and a second transfer touch sub-electrode (152) that are arranged side-by-side in the first direction (D1) and are electrically connected to each other. The first transfer touch sub-electrode (151) at least partially surrounds the first opening area (422), and the second transfer touch sub-electrode (152) at least partially surrounds the second opening area (421). At least part of the second trans
