Abstract: A keyboard equipped with light emitting structure comprises a plurality of keycap portions and a light guide command circuit board which includes an upper light guide plate, a lower light guide plate and a middle plate located between the upper and lower light guide plates. The upper and lower light guide plates have respectively an upper trigger portion and a lower trigger portion at one side facing the middle plate. The middle plate has a hollow zone corresponding to the upper and lower trigger portions, a plurality of coupling portions corresponding to the keycap portion and a plurality of apertures. The upper light guide plate also has an upper mask layer at one side facing the keycap portion and having a transparent zone. The command circuit board receives light from a light emitting unit and transmits the light to illuminate the keycap portion through the transparent zone.
