Touch substrate and display device

A display device, comprising a touch substrate;

• wherein the touch substrate comprises:
• a base substrate and a touch electrode layer located on the base substrate, wherein
• the touch electrode layer is of a mesh type structure comprising lead wires;
• the touch electrode layer comprises a plurality of first touch electrodes extending in a first direction and a plurality of second touch electrodes extending in a second direction;
• the first direction and the second direction intersect;
• a first touch electrode comprises a plurality of first touch sub-electrodes arranged in the first direction, and a second touch electrode comprises a plurality of second touch sub-electrodes arranged in the second direction;
• a first touch sub-electrode comprises a plurality of first touch electrode meshes, and a second touch sub-electrode comprises a plurality of second touch electrode meshes;
• the touch electrode layer further comprises a plurality of boundary meshes located between adjacent first touch sub-electrode and second touch sub-electrode;
• each boundary mesh comprises at least two first mesh lines;
• each first mesh line is provided with a first break;
• first breaks in the plurality of boundary meshes are configured to enable adjacent first touch sub-electrode and second touch sub-electrode to be insulated from each other;
• second mesh lines are arranged in a first touch electrode mesh and/or a second touch electrode mesh;
• the second mesh lines are provided with second breaks;
• and
• a mesh line in a boundary mesh is provided with a protruding part.
