1. A touch layer assembly, comprising:
a substrate layer;
a plurality of effective touch lines disposed on the substrate layer, at least one effective touch line extending along a first direction, the plurality of effective touch lines being arranged in a second direction intersecting the first direction; and
a plurality of sensing electrodes disposed on the substrate layer, a sensing electrode being coupled to at least one effective touch line, wherein
the sensing electrode includes a plurality of sensing main lines arranged in the second direction; at least one sensing main line extends along the first direction, and each of at least one sensing main line is composed of a plurality of first sensing line segments and a plurality of second sensing line segments that are alternately connected; at least one first sensing line segment extends along the first direction, and at least one second sensing line segment is oblique relative to the first direction;
the sensing electrode further includes a plurality of third sensing line segments connected to a sensing main line; at least one third sensing line segment is oblique relative to the first direction, and the at least one third sensing line segment has a free line end;
the plurality of sensing electrodes include a first sensing electrode and a second sensing electrode that are adjacent in the first direction; and in the first sensing electrode and the second sensing electrode, a disconnected point where two sensing main lines adjacent in a same extension direction are disconnected is located on a second sensing line segment at an end of a sensing main line of the two sensing main lines.
