A plurality of light-transmittable or transparent keycaps is disposed on a luminous keyboard. Between a bottom surface of each keycap and a circuit board, printed layers with various patterns corresponding to each keycap are disposed therebetween. The pattern of each printed layer is composed by a light-transmittable section and an opaque section. A light source module, which is composed by a light guide plate and a light emitting diode, can further be added to the luminous keyboard, under each keycap, so as to provide a self luminous light source for the keyboard. With the light-transmittable or transparent keycaps, the patterns or texts of the printed layers can be shown.
