The prism sheet includes an incident surface, an emitting surface opposite to the incident surface, and a plurality of micro-protrusions disposed on the incident surface in a random manner. Each micro-protrusion includes two side surfaces and a top arc. The side surface is a part of a circular cone whose circular bottom is a circular defined by the top arc. A plurality of planes defined by the top arcs parallel each other. The present invention also provides a backlight module using the prism sheet. The backlight module has high brightness performance and can prevent the light interference occurs.
