Abstract
Embodiments of the invention disclose a light source, a backlight, and a display device. The light source comprises at least a first light source structure, a second light source structure, and a third light source structure. One or combination of the first light source structure, the second light source structure, and the third light source structure is a laser light source structure. The laser light source structure comprises at least a laser source and a transparent diffusion tube diffusing light emitted by the laser source. The light-out direction of the laser source is constant with the extension direction of the central axis of the transparent diffusion tube. The laser light source structure is arranged in the light source.
