Abstract: A display device includes a display panel which displays an image with light, a light guide plate through which the light is guided and which guides the light to the display panel, and an absorption filter provided in plural. The light guide plate defines a light exit surface thereof through which the light is emitted to the display panel and a rear surface thereof opposite to the light exit surface. The absorption filters are provided on the rear surface of the light guide plate. The absorption filters on the rear surface of the light guide plate each include a first filter layer and a second filter layer. The first filter layer has a first refractive index. The second filter layer is on the first filter layer and has a second refractive index lower than the first refractive index.

Abstract: A display device includes a substrate including a display area and a bending area adjacent to the display area, a conductive layer disposed on the substrate in the bending area, where the conductive layer is configured to transmit driving signals from a driving circuit to a display unit, and a bending protective layer disposed on the conductive layer in the bending area. The bending protective layer includes conductive particles. In the case of a crack in the conductive layer, the conductive particles within the bending protective layer may freely move and fill into the conductive layer, preventing a decrease in display performance.

Abstract: A backlight assembly includes a light source which generates and emits light, and an optical member which is between the light source and a display panel of a display device and adjusts a path of the light emitted from the light source. The optical member includes a first base film, a second base film which faces the first base film and is closer to the display panel than the first base film, an optical pattern which is provided in plural spaced apart from each other and disposed between the first and second base films, a reflecting layer which is disposed on the optical patterns and reflects light incident to the optical member, and a wavelength conversion pattern between the first and second base films and alternately disposed with the optical patterns. The wavelength conversion pattern converts a source wavelength of the light emitted from the light source.
