Abstract
A light-emitting keyboard includes a bracket, keycaps, a circuit layer and a composite light-emitting layer. The keycaps are disposed on the bracket and connected to the bracket. The circuit layer is disposed between the keycaps and the bracket. The composite light-emitting layer is disposed under the bracket, and includes a substrate, a conductive layer and light sources. The substrate includes a connection portion and extension portions respectively connected to the connection portion. A gap is positioned between any two adjacent extension portions, and a width of the gap is greater than or substantially equal to a width of any of the two adjacent extension portions. The conductive layer is disposed on the substrate. The light sources are disposed on the extension portions.
