    Abstract: A backlight unit includes at least one light source configured to emit light and a light guide plate including a light incident surface and a light emitting emitting surface. The light from the light source is incident on the light incident surface and the incident light is emitted through the light emitting surface. A wavelength conversion unit is disposed between the light source and the light incident surface of the light guide plate. A lower cover is configured to cover at least part of a lower portion of a light incident surface of the wavelength conversion unit. An upper cover is configured to cover at least part of an upper portion of the light incident surface of the wavelength conversion unit.
