    Abstract: A window includes a folding portion foldable with respect to an imaginary folding axis extending in a first direction, a first non-folding portion, and a second non-folding portion spaced apart from the first non-folding portion in a second direction perpendicular to the first direction with the folding portion interposed therebetween. The folding portion includes a base portion and a plurality of protrusion portions disposed on the base portion and spaced apart from each other in the second direction. A width, in the first direction, of the folding portion is smaller than a width, in the first direction, of each of the first non-folding portion and the second non-folding portion.

    Abstract: Provided is a backlight unit including a printed circuit board, a light-emitting diode package, a diffusion plate, and a reflection sheet. The light-emitting diode package including a light-emitting part configured to generate a first light. The diffusion plate includes a first diffusion pattern provided on a first region corresponding to the light-emitting diode package and a second diffusion pattern provided on a second region to have a transmittance higher than that of the first diffusion pattern. The reflection sheet includes an absorption pigment configured to absorb a fraction of the first light with a specific wavelength and converting the first light to a second light, and the reflection sheet is configured to reflect the second light toward the first diffusion pattern. The backlight unit can have improved color coordinate uniformity.
