| description | The invention discloses a backlight module and a display module. The backlight module comprises a backlight source, a light guide plate and a light guide plate, the light guide plate comprises a side light incoming surface, a top light outgoing surface, a bottom reflecting surface and a side reflecting surface, and the side light incoming surface is arranged corresponding to the backlight source; wherein an ink layer is arranged on the side reflecting surface, the ink layer comprises a white ink layer and a black ink layer, and the black ink layer is arranged on the side, away from the side reflecting surface, of the white ink layer. The white ink layer can enable the light from the light guide plate to be reflected back into the light guide plate on the side reflecting surface, so that the light utilization rate of the light guide plate is improved; the black ink layer 132 can absorb light, reduce light leakage from the edge of the light guide plate, improve the problem of poor optics of bright lines on the |
