A backlight module (10, 20, 31) and an electronic device (30) are provided. When an optical assembly (12) is assembled, a first positioning portion (1213) and a second positioning portion (141) are cooperatively positioned to receive the optical assembly (12) within accommodating spaces (101, 201) via the backlight module (10, 20, 31), such that a distance between a light guide plate (121) and a backlight source (13) is less than or equal to a threshold value, preventing a circumstance from occurring during assembly in which the distance between the light guide plate (121) and the backlight source (13) is excessively large, causing the light guide plate (121) to not be able to completely receive light emitted by the backlight source (13). The backlight effect of the light guide plate (121) is thus improved, the assembly precision may be increased and assembly difficulty may be decreased.
