To provide a light emission keyboard for preventing the light quantity of a beam from being wasted.
A light emission keyboard includes: a plurality of keys, a thin film switch circuit; and a light emission module to be used for generating a beam. The thin film switch circuit generates a signal after being induced by a key, and the thin film switch includes a plurality of light guide areas, and at least one light guide area among the plurality of light guide areas has a light guide structure, and any light guide structure is not arranged at the position of a key connection point corresponding to the key in at least one light guide area. Therefore, it is possible to prevent a beam to be generated by the light emission module from being blocked by the key connection point, and from being wasted.
