Abstract
A light-emitting substrate includes a base, a first conductive pattern layer disposed on the base and a second conductive pattern layer disposed on a side of the first conductive pattern layer away from the base. The first conductive pattern layer includes first signal lines. The second conductive pattern layer includes lamp bead pads. The lamp bead pads include first lamp bead pads and at least one second lamp bead pad. A vertical projection of each first lamp bead pad on the base at least partially overlaps with a vertical projection of a first signal line on the base. A vertical projection of each second lamp bead pad on the base is outside vertical projections of the first signal lines on the base. A distance between a first lamp bead pad and the base is substantially the same as a distance between a second lamp bead pad and the base.
