Beschreibung
Zusammenfassung:	The invention relates to a backlight module which comprises a reflecting cover, a light emitting diode and a reflecting piece, wherein the reflecting cover is arranged at one side of the backlight module, and a reflecting curve is arranged on the backlight module; the light emitting diode is arranged at the focal point of the reflecting curve, and the light reflecting surface of the light emitting diode faces towards the reflecting curve; light emitted by the light reflecting surface of the light emitting diode can be reflected by the reflecting curve to form a parallel light source; and the reflecting piece can be used for reflecting the parallel light source so as to guide the parallel light source to a light emitting surface opposite to a bottom surface where the reflecting piece is located.
