[0057] For example, continue to refer to Figure 3-Figure 6 The wiring structure 200 includes a support member 210 and a connecting wire 220. The support member 210 is disposed on the surface of the cover plate 300 facing the light emitting component 120.

[0058] Reference Figure 3 and Figure 5 In some possible embodiments, the light-emitting component 120 includes a light-emitting portion 121 and a adapter portion 122, the adapter portion 122 is electrically connected to one end of the light-emitting portion 121 close to the support member 210, and the adapter portion 122 is electrically connected to the second end of the connecting wire 220, so that the light-emitting portion 121 is electrically connected to the driving chip 130 through the adapter portion 122 and the connecting wire 220.
[0059] Exemplarily, the light emitting portion 121 includes a circuit body 1211, a bonding piece 1212 and a light emitting unit 1213. The circuit body 1211 is disposed on the first surface of the substrate 110, and the surface of the circuit body 1211 away from the substrate 110 is electrically connected to the light emitting unit 1213 through the bonding piece 1212.
[0060] The light-emitting unit 1213 can be set as a light-emitting diode type light-emitting unit 1213, the number of the light-emitting unit 1213 can be set to multiple, the multiple light-emitting units 1213 are arranged in multiple rows and columns, the number of the bonding parts 1212 is set to multiple, the multiple bonding parts 1212 are arranged one by one with the multiple light-emitting units 1213, and each light-emitting unit 1213 is electrically connected to the circuit body 1211 through a bonding part 1212.
[0061] A filling layer 123 is also provided on the surface of the circuit body 1211 facing away from the substrate 110. The surface of the filling layer 123 facing away from the circuit body 1211 is connected to the cover plate 300. The filling layer 123 accommodates multiple bonding parts 1212 and multiple light-emitting units 1213. The filling layer 123 can be set as a black matrix (Black Matrix, abbreviated as BM) to separate the multiple light-emitting units 1213 through the filling layer 123, thereby reducing the possibility of mutual interference between the multiple light-emitting units 1213.
