Claim 18:
19. The method for manufacturing the backplane according to claim 16, wherein the circuit structure layer includes a plurality of pads, and forming the first reflective layer and the plurality of light-emitting diode chips on the substrate includes:
forming the plurality of light-emitting diode chips on the substrate, a light-emitting diode chip in the plurality of light-emitting diode chips being electrically connected to two of the plurality of pads;
providing a reflective sheet;
forming an adhesive film on a non-functional surface of the reflective sheet;
attaching a first protective film onto the adhesive film;
forming a plurality of through holes in the reflective sheet, the adhesive film and the first protective film, each through hole penetrating the reflective sheet, the adhesive film and the first protective film, so as to obtain the first reflective layer, an adhesive layer and a first protective layer;
tearing off the first protective layer; and
attaching the first reflective layer to a bearing surface of the substrate through the adhesive layer, so that the plurality of light-emitting diode chips are located in the plurality of through holes in one-to-one correspondence.
