A backlight module including a light guide plate, a circuit board, an electronic component, a reflective sheet, a light-shielding sheet, and a light-emitting component is provided. The light guide plate includes an escape opening and a light-source opening. The circuit board is disposed under the light guide plate. The electronic component is electrically connected to the circuit board, and at least a part of the electronic component is located in the escape opening. The reflective sheet is disposed on a rear surface of the light guide plate and between the light guide plate and the circuit board. The light-shielding sheet is disposed on a light emitting surface of the light guide plate opposite to the rear surface. The light-emitting component is disposed in the light-source opening. A luminous keyboard using this backlight module is also provided.

The present invention provides a light guide plate and an input apparatus. The light guide plate includes a light guide body, at least one first opening structure, and at least one second opening structure. The first opening structure passes through the light guide body and includes at least one first closed end. The second opening structure passes through the light guide body and includes at least one second closed end. The first closed end and the second closed end face each other. The first closed end partially overlaps the second closed end on at least one first axis, the first closed end and the second closed end are disposed parallel to each other on at least one second axis, and the first axis is substantially perpendicular to the second axis.
