Abstract: A keyboard device includes a keyboard module and an illumination module. The keyboard module includes plural first keys and at least one second key. The illumination module includes a light guide plate and a circuit board. The light guide plate includes plural first mapping zones and a second mapping zone. The first mapping zones are located under the corresponding first keys. The second mapping zone is located under the second key. Moreover, at least one side-view light-emitting element and at least one top-view light-emitting element are installed on the circuit board. The side-view light-emitting element emits a first light beam. The top-view light-emitting element emits a second light beam. The first light beam is extracted through the corresponding first mapping zone and transferred to the corresponding first key. The second light beam is transferred to the second key.
