Abstract: Disclosed are a functional reflective sheet for an LCD backlight unit and a method of fabricating the same. A bonding sheet is laminated on one lateral surface of a substrate sheet, and spherical-shaped coating particles are coated on the bonding sheet, thereby preventing a coating solution layer from being formed on a surface of the coating particle to acquire a reflective sheet having high roughness, so that light diffusion can be enhanced. In addition, a drying process is omitted and a curing process is omitted or shortened, so that the productivity can be improved. In addition, the pressing of a conventional reflective sheet when the reflective sheet makes a close contact with the light guide plate is minimized. In addition, the surface of the reflective sheet is curved, so that the light diffusion is provided, thereby preventing defects, such as lamp mura or the wrinkle, of an outer appearance of the reflective sheet from being viewed by a light source in a backlight unit. The present invention includes a white substrate sheet serving as the substrate; the bonding sheet laminated on at least one lateral surface of the white substrate sheet and having a self-bonding property; and the spherical coating particles fixed onto the bonding sheet in a layered arrangement structure.
