    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.
