Abstract: A color conversion member, a backlight unit and a display device are discussed. The color conversion member including a reflection partition wall and color conversion material is disposed between a light source and a light path control sheet, so that the thickness of the backlight unit can be reduced, and the wavelength conversion function and the light guide function can be easily implemented by the color conversion member. In addition, by adjusting the thickness of the reflection partition wall and the thickness of the color conversion material, or by adjusting the structure of a light source protection layer located under the color conversion member, it is possible to easily implement various optical properties needed according to the backlight unit without increasing the thickness of the backlight unit.
