Abstract: Embodiments provide a window and a display device including the window. The window includes a base substrate including a first surface and a second surface which face each other, and a filling portion. The base substrate has a concave portion defined on at least one of the first surface and the second surface, a difference between a refractive index of the base substrate at a wavelength of about 589 nm and a refractive index of the filling portion is less than or equal to about 0.02, a difference between an Abbe No. of the base substrate and an Abbe No. of the filling portion is less than or equal to about 5.0, and the filling portion fills the concave portion. The window and the display thus exhibits satisfactory folding properties and impact resistance, as well as improved optical properties and display quality that prevent reflection color from being viewed.

Abstract: A backlight unit includes a light source. A light guide plate receives light supplied from the light source at an incident light part of the light guide plate. A reflective sheet is positioned below the light guide plate and reflects light upwardly. A diffuser sheet is formed on the light guide plate and diffuses the light to transfer the diffused light upwardly. The diffuser sheet includes a color material, and a concentration of the color material within the diffuser sheet is dependent upon a distance from the incident light part.
