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 substrate including a display area and a peripheral area. A display element is disposed in the display area and is electrically connected to a thin film transistor. A power supply line is disposed in the peripheral area. An insulating layer covers a portion of the power supply line. A barrier layer is disposed on the insulating layer and includes a first side surface facing the display area and a second side surface facing away from the display area. At least one of the first side surface or the second side surface includes a concavo-convex surface. The barrier layer forms a step difference with respect to an upper surface of the insulating layer. An end of the insulating layer is positioned beyond the second side surface of the barrier layer on a side of the barrier layer facing away from the display area.
