## Abstract

A display panel includes a display area (DA) and a peripheral area (PA) surrounding the display area (DA). The display area (DA) includes a second area and a first area that includes first pixel units disposed around holes, where the second area includes second pixel units and K data lines. The second pixel units include M columns*N rows of light emitting devices, M*N bottom drive circuits located at lower layers of the light emitting devices, and M*N anode leads connecting the light emitting devices to the bottom drive circuits. Intervals between some or all of the adjacent light emitting devices are greater than dimensions of the bottom drive circuits corresponding to the light emitting devices, and therefore there are gaps between the some or all of the second pixel units.
