Claim 1:
2. The light emitting keyboard as claimed in claim 1, wherein said backlight module further includes a semi-light shielding layer coated on a surface of said first light guide plate opposite to said light source circuit board, said light shielding layer having a semi-light shielding region disposed below and corresponding in position to said through holes and covering said first light guide plate, and a plurality of light transmitting regions corresponding in position to said perforation groups, said backlight module further including a plurality of reflective regions coated on a surface of said second light guide plate and corresponding in position to said light transmitting regions, and wherein the light emitted from said first light-emitting members and transmitted in said first light guide plate passes through said light transmitting regions and said perforation group to project upwardly onto said key caps, and the light emitted from said second light-emitting members and transmitted in said second light guide plate is repeatedly reflected between said reflector plate and said reflective regions, and then passes upwardly through said first light guide plate, said semi-light shielding region, said through holes and said thin film circuit board from an area of said second light guide plate not covered by said reflective regions to project onto said frame body.
