| description | The invention provides a backlight source, a display panel and a display device. The backlight source comprises at least one light source, and further comprises a light direction change part, the light direction change part is arranged at a light-out side of the light source and used for changing a propagation direction of the light emitted by the light source through at least two different lightdirection change modes; the backlight source can change the propagation direction of the light emitted by the light source through at least two different light direction change modes by arranging thelight direction change part at the light-out side of the light source, thereby enabling a backlight direction of the backlight source to realize the change of at least two modes, and then enabling thedisplay device adopting the background source to realize the switching of at least two display visual angles, and watching demands of audiences under different scenes are satisfied. The display paneland the display device adop |
