PRISM SHEET AND BACKLIGHT ASSEMBLY AND LIQUID CRYSTAL DISPLAY COMPRISING THE SAME

摘要

A prism sheet, and a backlight assembly and a liquid crystal display device comprising the same are provided to form diffusion beads between prism arrays, which are formed on a transparent base for obtaining light refraction, light collection, and beam diffusion functions, thereby simplifying a thin film of the liquid crystal display device. A prism sheet(100) comprises a transparent base(10), prism arrays(20) and multiple diffusion beads(30). The prism arrays are formed with multiple stereoscopic structures on the transparent base. The diffusion beads are placed between the prism arrays. The diffusion beads have the same size in the same row. The diffusion beads have different sizes in the different rows. Multiple projections are placed on surfaces of the diffusion beads. The diameter of the diffusion beads is 3 to 50mum. The diffusion beads include diffusing agents. The diffusing agents are organic particles or inorganic particles.
