  • Patent number: 10025021
    Abstract: Provided are a display device and a method of fabricating the display device. The display device includes a display panel, a backlight unit, and a light emitting sheet. The backlight unit is disposed under the display panel to provide light to the display panel. The light emitting sheet is disposed between the display panel and the backlight unit. The light emitting sheet includes a lower film, a first light emitting resin pattern layer, an upper film, and a second light emitting resin pattern layer. The first light emitting resin pattern layer is disposed on the lower film and includes a plurality of first protrusions and a plurality of first grooves defined between the first protrusions. The upper film is disposed on the first light emitting resin pattern layer. The second light emitting resin pattern layer is disposed between the first light emitting resin pattern layer and the upper film.

  • Patent number: 9116281
    Abstract: Provided are a complex optical film and a light source assembly including the same. The complex optical film includes a first substrate, a light shielding layer formed on a bottom surface of the first substrate, an optical pattern layer formed on a top surface of the first substrate and including concavo-convex portions, a second substrate disposed on the first substrate, and a first adhesive layer disposed under the second substrate, wherein the light shielding layer includes a binder and organic particles and inorganic particles dispersed in the binder, the convex portions of the optical pattern layer at least partially penetrate into the first adhesive layer to be combined with the first adhesive layer, and a low-refraction area having a lower refractive index than the optical pattern layer and the first adhesive layer is defined between the first adhesive layer and the optical pattern layer.
