摘要： A light guiding structure, a manufacturing method thereof, a light source assembly and a display device are provided. The light guiding structure includes a first light guiding layer including a light emitting surface and a first surface, and a second light guiding layer including a second surface. The light emitting surface includes a first inclined surface having a first angle with respect to the first surface. A second inclined surface is on a side of the second surface away from the first light guiding layer and has a second angle with respect to the second surface. Refractive indexes of the first and second light guiding layers are respectively n1 and n2, n1>n2; a direction of light, which enters the second light guiding layer after being reflected by the first inclined surface, and is incident to and reflected by the second inclined surface, is substantially perpendicular to the first surface.

摘要： A light convergence structure includes light convergence portions. Each light convergence portion includes a frustum structure and a plano-convex structure. The frustum structure includes a first end surface and an opposite second end surface. An area of the first end surface is less than an area of the second end surface. The plano-convex structure is on the second end surface of the frustum structure. The plano-convex structure includes a flat surface and an opposite convex spherical surface. The flat surface is in contact with the second end surface. An area of the flat surface is equal to the area of the second end surface. The first end surfaces of the light convergence portions are coplanar and together define a light incident surface of the light convergence structure.
