In the related art, the chip assembly may be fixed by COF technology, for example, the electronic device may include a display panel 101, a housing 102, and a circuit board 103, wherein the circuit board 103 may be connected to an edge of the display panel 101, and connected to the other side of the display panel 101 after being bent along the edge. Since the circuit board 103 needs to be connected to the display panel 101 and the housing 102 supports the display panel 101, the avoiding space 1021 needs to be formed on the housing 102 so that the circuit board 103 can be connected to the surface of the display panel 101 facing the housing 102.

However, in the related art, the avoiding space 1021 formed on the housing 102 may cause the strength of the housing 102 to be reduced, and cannot provide a complete supporting plane for the display panel 101, so that when the electronic device is dropped or impacted by an external force, an unsupported area of the display panel 101 is easily twisted or deformed, which is not beneficial to prolonging the service life of the electronic device.

Accordingly, the present disclosure provides an electronic device 100, as shown in fig. 2 to 4, the electronic device 100 may include a display panel 1, a housing 2, and a flexible wiring board 3.
