The illuminated keyboard according to item 8 of the scope of patent application, wherein the lower surface of the light source circuit layer is a first reflective layer, and the first reflective layer reflects a portion of the first light ray leaving the first light guide plate, Return the reflected part of the first light to the first light guide plate. The illuminated keyboard according to item 8 of the scope of patent application, wherein the lower surface of the light source circuit layer is a third light-shielding layer, and the third light-shielding layer shields a portion of the first light from the first light guide plate, A portion of the first light beam blocked by the stopper travels to an upper surface of the light source circuit layer. According to the light-emitting keyboard according to item 1, 2, or 8, in the patent application scope, wherein the first backlight module further has a first light-shielding layer, the first light-shielding layer has a first light-shielding layer light-transmitting pattern, and when the When the first light travels to the first light-transmitting region of the first surface layer, the light-transmitting pattern of the first light-shielding layer is displayed brightly in the first light-transmitting region of the surface layer. The illuminated keyboard according to item 1, 2, or 8 of the scope of the patent application, further comprising an adhesive layer, the adhesive layer is used to adhere the first reflective layer to the first light guide plate to avoid the first light guide plate. A partial area of light transmission.
