Abstract: PURPOSE: A diffuse sheet for a back light unit and a manufacturing method thereof are provided to include an acrylic bead and an UV curable resin layer, thereby minimizing the deformation of an optical sheet by heat and preventing the deformation by heat when driving as being assembled in the backlight unit. CONSTITUTION: A functional diffusion sheet(100) for a backlight unit is comprised of a polyester film member(110) and a functional diffusion layer(120) being laminated. The functional diffusion layer(120) removes the bright line by diffusing the light transmitted from a lamp. The functional diffusion layer(120) comprises a UV curable resin(121) and an acrylic bead(122). In the UV curable resin(121), the acrylic bead(122) exists in a dispersed status. The acrylic bead(122) of the functional diffusion layer(120) has an average particle of 0.1-15μm, has a medium weight dispersion distribution, and a difference between the maximum particle and the minimum particle is less than 10um.

Abstract: PURPOSE: A light diffusion sheet for a backlight unit is provided to obtain high scratch resistance, an antistatic property, and high intensity by including a functional diffusion layer. CONSTITUTION: A functional diffusion layer(120) is formed on one side of a light transmissive base member(110) and includes ultraviolet curable resins and light diffusion corpuscles. An anion surfactant film(130) is formed on the surface of the functional diffusion layer. The light transmissive base member includes a base film(111) and a light transmissive coating layer(112,113).
