The invention provides a reflector. The reflector is characterized in that the reflector comprises a reflector body and a groove disposed on the reflector body. The invention also provides a backlight module and a television set comprising the backlight module. According to the technical scheme provided by the invention, the light utilization rate can be improved effectively by restricting the emergent light angle of the LED (light emitting diode) lamp through a groove in a small range of each LED lamp. Meanwhile, the energy distribution in each direction can be controlled by controlling the groove shape so as to improve the freedom of LED lamp arrangement to a certain extent. The restriction effect of the groove to the light source can also solve the problem of insufficient light mixing to a certain extent so as to solve the problem of subjective light shadow existing in the common direct-type backlight module; in addition, the requirement of 3D display for dynamic control of the backlight module area is well met, the contrast and resolution of the dynamic area are enhanced, and the comprehensive performance of 3D display equipment is improved.
