Circuit board and display apparatus

A circuit board having a main body area, a bending area and a bonding area that are connected in sequence;

• the circuit board comprising a plurality of conductive layers that are arranged in sequence, wherein
• the circuit board comprises a first signal line, the first signal line includes a plurality of first traces and a second trace;
• the first traces are disposed in the main body area and extend in a first direction;
• the second trace is disposed in the bending area, with an end extending to the main body area and connected to a first trace, and another end extending to the bonding area;
• the first direction is from the main body area to the bending area;
• and
• the plurality of first traces are disposed in different conductive layers;
• orthographic projections of at least two first traces on a reference plane overlap, and two ends of one of overlapped portions are connected to two ends of the other of the overlapped portions;
• the reference plane is parallel to surfaces of the conductive layers.
