Abstract: Disclosed is a direct type reflective sheet structure, comprising a reflective sheet, on which a plurality of light emitting diode light sources are arranged in an array. A plurality of triangular prism-shaped microstructures is arranged at intervals on the reflective sheet around each of the light emitting diode light sources. Each of the microstructures has a reflective surface facing the light emitting diode light source to reflect light emitted by the light emitting diode light source. Further disclosed is a direct type backlight module. By implementing the embodiment of the present invention, it can avoid the appearance of color deviation on the display panel and reduce the loss of light.
