Abstract: A display device includes a micro-lens film which has a high fill-factor and a high luminance ratio and prevents generation of moiré. The display device includes a display panel configured to display an image, a plurality of Light Emitting Diodes (LEDs) configured to generate light to supply light to the display panel, a light guide panel configured to guide light to the display panel, and a micro-lens film including a base film that concentrates and diffuses light emitted from the light guide panel, a lens unit at an upper surface of the base film, and a back-coating film at a lower surface of the base film. The lens unit includes unit block groups randomly arranged at the upper surface of the base film, each unit block group containing randomly arranged fixed-shape lenses having different sizes, and micro-beads randomly formed on surfaces of the fixed-shape lenses.

Abstract: A display device and a method of fabricating a reflective sheet for the same are provided. The display device includes: a display panel to display an image, a plurality of light emitting diodes (LEDs) to: generate and supply light to the display panel, a light guide plate to guide the light to the display panel, and a reflective sheet to reflect light toward a cover bottom below the LEDs toward the light guide plate, the reflective sheet including: a reflective layer, first and second skin layers respectively on upper and lower portions of the reflective layer, the first and second skin layers each including an embossing surface including a plurality of first reflective patterns to: prevent adhesion between the reflective layer and the light guide plate, and increase efficiency of light, and the reflective layer including a plurality of second reflective patterns, each including a filler in an air layer.
