Abstract: The technology of this disclosure relates to a stacked structure, a display screen, and a display apparatus. The stacked structure includes a substrate, a drive chip, and a pixel unit that are stacked. The substrate has a first surface. A line layer is disposed on the first surface, the drive chip is disposed on a surface that is of the line layer and that faces away from the first surface, and the pixel unit and a corresponding drive chip are stacked. A sub-pixel located in each pixel unit is separately electrically connected to the line layer and the corresponding drive chip to form a light-emitting loop.
