Abstract: A semiconductor package including a first semiconductor die, a second semiconductor die, a first insulating encapsulation, a dielectric layer structure, a conductor structure and a second insulating encapsulation is provided. The first semiconductor die includes a first semiconductor substrate and a through silicon via (TSV) extending from a first side to a second side of the semiconductor substrate. The second semiconductor die is disposed on the first side of the semiconductor substrate. The first insulating encapsulation on the second semiconductor die encapsulates the first semiconductor die. A terminal of the TSV is coplanar with a surface of the first insulating encapsulation. The dielectric layer structure covers the first semiconductor die and the first insulating encapsulation. The conductor structure extends through the dielectric layer structure and contacts with the through silicon via.

Abstract: A light source module includes a light guide plate, a light-emitting element, and first and second prism sheets. One of the light-emitting surface and the bottom surface of the light guide plate has strip-shaped microstructures. The bottom surface has bottom microstructures, and the angle between the first surface of each bottom microstructure and the bottom surface is 1° to 17°. The first prism sheet is disposed on the light-emitting surface and between the light-emitting surface and the second prism sheet and includes first prism rods. The second prism sheet includes second prism rods. The aspect ratio of the strip-shaped microstructure is greater than 0.2. The angle between the maximum luminance direction of the light from the light-emitting surface and the normal direction of the light-emitting surface is less than 70°. The light-emitting angle range is less than 40°. A display device including the light source module is also provided.
