The invention discloses a front frame and a back light module. The front frame comprises at least one stacked plate which is stacked with the front frame. The invention adds the stacked plate on the front frame which the stacked plate is stacked with, so that the structure thickness of the front frame is increased, thereby increasing the total strength. In case that the strength is increased, the plate thickness of the front frame can be reduced, or some structures of the front frame like side walls can be removed, or structure material with low cost can be employed to achieve the aim of reduction of material cost.
