BACK LIGHT ASSEMBLY AND DISPLAY DEVICE HAVING THE SAME

摘要

A back light assembly and a display device having the same are provided to minimize the leakage light toward the circumference by using a reflexive reflection sheet. Plural spot light sources(210) are received at a receiving container and generate the light beam. A diffusing plate(410) is arranged at the upper portion of the spot light sources. A self-reflection sheet(300) is arranged at the lower side of the spot light sources and reflects the light beam toward the light incidence direction. The self-reflection sheet includes a base sheet and plural transparent beads formed at a side of the base sheet. The transparent beads are made of glass. The self-reflection sheet includes also a reflection layer formed between the base sheet and the transparent beads. The self-reflection sheet also includes a base sheet and plural prism patterns formed at a side of the base sheet.
