Abstract
A luminous keyboard device includes plural keys, a supporting plate, a light-emitting element, and a light guide plate. The supporting plate has a supporting plate opening, and the supporting plate opening has a light-guiding slant surface. The light-emitting element is inserted into the supporting plate opening for emitting plural light beams. When the plural light beams are emitted by the light-emitting element, the plural light beams are guided by the light-guiding slant surface to be introduced into the light guide plate, and the plural light beams are directed to the plural keys to illuminate the plural keys. Consequently, the light amount of the light beams to be introduced into the light guide plate will be increased.
