Abstract
A display device includes: a display panel which displays an image with light; a light source which generates and emits the light; a light guide plate which receives the light emitted from the light source on a first surface of the light guide plate and emits the received light through a second surface of the light guide plate different from the first surface; and a light converting unit between the light source and the light guide plate. The light converting unit includes: a phosphor which converts a first color of the light emitted from the light source to a second color different from the first color; a transparent base in which the phosphor is disposed; and a transparent film between the light source and the phosphor disposed in the transparent base, the transparent film being attached to a surface of the transparent base.
