Beschreibung
Zusammenfassung:	A backlight module is disclosed. The backlight module includes a substrate, a plurality of light emitting diodes and a plurality of patterns. The light emitting diodes are disposed on the substrate. The patterns are located at one side of the light emitting diodes opposite to the substrate. The patterns respectively correspond to the light emitting diodes, and the patterns are respectively formed with two elongated geometric patterns intersect with each other. The light emitting diodes have an arrangement direction. The angle between the long axis of the elongated geometric pattern and the arrangement direction is greater than 0 degrees and less than 90 degrees.
