The phosphor grid dots are capable of generating excitation light after being irradiated by light from a light source. The reflection layer is configured to reflect the excitation light of the phosphor grid dots to the light guide plate body. Embodiments of the present disclosure also provide a front light source module, a display module and a display device.
