    Abstract: A display device includes a backlight assembly and a display panel which displays an image. The backlight assembly includes a light emitting unit which generates light, and an optical member which adjusts a path of the light incident thereto and outputs the light toward the display panel. The optical member includes a first base film to which the light is incident, a second base film closer to the display panel than the first base film and for which are defined first and second areas alternately disposed, a first optical pattern between the first and second base films at the first area, where the first optical pattern refracts therein the light incident to the first base film, and a second optical pattern between the first and second base films at the second area, where the second optical pattern scatters the light incident to the first base film.

    Abstract: A display device includes a folding area foldable about a folding axis and a non-folding area proximate to the folding area. The display device includes a display module that displays an image and a glass window that is disposed over the display module that includes a patterned glass. The patterned glass includes a pattern portion including a groove pattern provided on one surface of the patterned glass to correspond to the folding area and a non-pattern portion disposed adjacent to the pattern portion to correspond to the folding area. The pattern portion has a thickness that is smaller than or equal to one-half a thickness of the non-pattern portion.
