1. A glass backplane, comprising:
a tempered glass substrate, two opposite sides of the tempered glass substrate being a first side and a second side;
a light-shielding layer disposed on a surface of the first side of the tempered glass substrate, two opposite sides of the light-shielding layer being a first side and a second side, and the second side of the light-shielding layer being closer to the tempered glass substrate than the first side of the light-shielding layer;
a reflective layer disposed at the first side of the light-shielding layer; and
a heat-dissipating layer and a destaticizing layer disposed between the light-shielding layer and the reflective layer, wherein the destaticizing layer is disposed on a surface of the first side of the light-shielding layer, the heat-dissipating layer is disposed on a side of the destaticizing layer away from the light-shielding layer, a material of the heat-dissipating layer includes at least one of graphite, copper, aluminum and silver, and a material of the destaticizing layer is a metal;
wherein the reflective layer includes a first sub-layer and a second sub-layer that are stacked, and the second sub-layer is closer to the light-shielding layer than the first sub-layer;
the first sub-layer includes a base and reflective particles dispersed in the base, a material of the base includes at least one of acrylic resin and polymethyl methacrylate, and a material of the reflective particles includes at least one of titanium dioxide, zinc oxide and zirconium oxide; and
a material of the second sub-layer is polyethylene glycol terephthalate.
