| Zusammenfassung: | The invention provides a backlight module which comprises a substrate and a plurality of light-emitting units, and the light-emitting units are arranged on the substrate. The light emitting unit includes the following elements. The light-emitting element is arranged on the substrate. The lower layer structure is arranged on the substrate and surrounds the side face of the light-emitting element, the inner side of the lower layer structure is provided with a reflection structure, and the reflection structure is used for reflecting light rays from the side face of the light-emitting element upwards. The upper layer structure is arranged above the lower layer structure, the upper layer structure comprises a transparent material, the upper layer structure is provided with a refracting surface, and the refracting surface is used for reducing divergence of light rays, so that the light rays are emitted from the upper surface of the upper layer structure in the front view direction of a user. Therefore, the purpose |
