The present invention provides a backlight module and a display device, comprising: a light guide plate (100) including a light-entering surface (101), a light-exiting surface (102) and a back surface (103); a LED light bar (200) including a plurality of LED lamps (201) arranged at intervals, the LED light bar being arranged at a side of the light guide plate so as to emit the light to the light-entering surface of the light guide plate, and a gap (G) being provided between the LED light bar and the light guide plate; and a reflection member (400) arranged outside the gap, a reflection surface of the reflector facing the gap so as to reflect the light from the LED light bar toward the light-entering surface of the light guide plate, wherein first regions (4001) and second regions(4002) are arranged on the reflection surface of the reflection member at intervals, a position of the first region corresponds to a position of the LED lamp, a position of the second region corresponds to a position of a interval between the plurality of LED lamps and/or a position outside the LED lamps at the end of the LED light bar, and the first region has a reflectivity less than the second region. According to the present invention, it is able to appropriately reduce the difference between the intensity of the incident light at the intervals between the LED lamps and the intensity of the incident light at the LED lamps, thereby to achieve even light intensity and reduce hot spots. |
