A light-emitting keyboard includes: a key cap with a key cap light transmission pattern; a keyboard surface layer with a first surface light transmission area; a first backlight module with the first backlight The module has: a first light source that emits a first light; and a first light guide plate, the first light guide plate is disposed above the surface layer of the keyboard, the first light guide plate transmits the first light Light, so that the first light can reach the transparent area of the first surface layer; a second light source, the second light source is directed to the keycap, to provide a second light to the keycap light-transmitting pattern, so that the key The light transmitting pattern of the cap emits light; and a light source circuit layer, which is located on the side of the first light guide plate facing away from the surface layer of the keyboard, and the first light source and the second light source are respectively disposed under the light source circuit layer Surface and upper surface. The light-emitting keyboard as described in item 8 of the patent application range, wherein the lower surface of the light source circuit layer is a first reflective layer, and the first reflective layer reflects part of the first light leaving the first light guide plate, The reflected part of the first light is returned into the first light guide plate. The light-emitting keyboard according to item 8 of the patent application range, wherein the lower surface of the light source circuit layer is a third light-shielding layer, and the third light-shielding layer shields part of the first light leaving the first light guide plate, The first light rays travel to the upper surface of the light source circuit layer by blocking the shielded part. The light-emitting keyboard as described in item 1, 2 or 8 of the patent application range, wherein the first backlight module further has a first light-shielding layer, and the first light-shielding layer has a first light-shielding layer light-transmitting pattern. When the first light travels to the light-transmitting area of the first surface layer, the light-transmitting pattern of the first light-shielding layer is brightly displayed in the light-transmitting area of the first surface layer. The luminous keyboard as described in item 1, 2 or 8 of the scope of patent application, which further includes an adhesive layer which adheres the first reflective layer to the first light guide plate to avoid the first A partial area for light transmission.
