摘要： A keyboard includes a transparent board, keyswitches, and a backlight module. The keyswitches could move upward and downward relative to the transparent board. At least one keyswitch includes a cap and a light exciting layer disposed in a transparent concave portion of the cap. The backlight module is disposed under the transparent board and includes a blue-light emitting diode, a reflection sheet, and a light guide plate having a light entrance surface, a light exit surface, and a bottom surface. The blue-light emitting diode is disposed corresponding to the light entrance surface for emitting light into the light guide plate. The reflection sheet is disposed on the bottom surface for reflecting light in the light guide plate to emit out of the light exit surface and then pass through the transparent board and the transparent concave portion, so that the light exciting layer could be excited to emit light.
