A display device is provided to reduce an amount of light incident on a display panel by being directly reflected upon an upper side of a light guide plate. A light source(200) is arranged on one side of a light guide plate(100). A reflection barrier layer(400) is arranged on an upper side of the light guide plate. A display panel is arranged on the light guide plate. The reflection barrier layer closely adheres to the light guide plate. Thickness of the reflection barrier layer corresponds to thickness, which causes destructive interference toward light emitted from the light guide plate by being emitted from the light source. A wavelength of the light is between 500nm and 600nm. A refractive index of the reflection barrier layer is lower than a refractive index of the light guide plate. |
