1. A keyswitch backlight structure, comprising:
a light-guiding layer, the light-guiding layer having a bottom surface, a light-emitting surface opposite to the bottom surface, and a surface microstructure formed on the light-emitting surface;
a reflective layer, disposed under the light-guiding layer opposite to the bottom surface; and
a transparent adhesive layer, closely attached to and between the reflective layer and the light-guiding layer corresponding to the surface microstructure;
wherein a low reflective layer is formed corresponding to the surface microstructure on a surface of the reflective layer facing the light-guiding layer, and a reflectance of the low reflective layer is lower than a reflectance of the reflective layer.
