1. A light emitting keyboard, comprising:
a frame including a frame body that is translucent, and a plurality of key holes formed in said frame body;
a thin film circuit board that is disposed under said frame and that is light transmissible;
a support plate disposed under said thin film circuit board, and including a plate body, a plurality of perforation groups formed in said plate body and corresponding to said key holes, and a plurality of through holes formed in said plate body and spaced apart from said perforation groups;
a plurality of key modules respectively disposed in said key holes and corresponding to said perforation group, each of said key modules including a keycap, a connecting member pivotally connected between said keycap and said support plate, and a resilient member abutting between said key cap and said thin film circuit board; and
a backlight module disposed under said support plate and including a light source circuit board, a first light guide plate disposed on top of said light source circuit board and located below said plate body, a second light guide plate disposed under said light source circuit board, a plurality of first light-emitting members disposed on said light source circuit board and extending upwardly through said first light guide plate, a plurality of second light-emitting members disposed on said light source circuit board opposite to said first light-emitting members and extending downwardly through said second light guide plate, and a reflector plate disposed under said second light guide plate, wherein light emitted from said first light-emitting members is transmitted in said first light guide plate, and then passes upwardly through said perforation groups, said thin film circuit board, and said key holes to project onto said key caps, and light emitted from said second light-emitting members is transmitted in said second light guide plate, is reflected by said reflector plate, and then passes upwardly through said first light guide plate, said through holes and said thin film circuit board to project onto said frame body.
