Abstract
Embodiments of the present disclosure provide a touch substrate and a touch display device. In the touch substrate, the first touch control electrodes are provided with the shadow elimination structures at the first intersections, and the orthographic projections of the shadow elimination structures on the base substrate cover the orthographic projections of the connection through holes on the base substrate, so that shadows of the connection through holes can be shielded by the shadow elimination structures, when the user watches the touch substrate from the side, away from the signal line layer, of the base substrate, and thus the ghosting shadow problem of the connection through holes can be resolved.
