Since thenon-display area 200 is disposed around thedisplay area 100, the staticelectricity discharge layer 10 is disposed around thedisplay area 100 of the display panel. As shown in fig. 1, the staticelectricity derivation layer 10 is respectively disposed on the left and right sides of thedisplay area 100 of the display panel, the staticelectricity derivation layer 10 includes a plurality of derivationlayer body substructures 121, and fig. 3 exemplarily shows a schematic cross-sectional structure diagram in which the derivationlayer body substructures 121 are respectively disposed on the left and right sides of thedisplay area 100 of the display panel, where the derivationlayer body substructures 121 include a first derivationlayer body substructure 122 and a second derivationlayer body substructure 123.
