Abstract: A light-guide plate includes a light-guide member through which light is guided to exit from an upper surface of the light-guide member; and a high refractive index member covering a lower surface of the light-guide member which is opposite to the upper surface thereof, the high refractive index member including: a first high-refractive layer and a second high-refractive layer having refractive indices equal to each other, each of the refractive indices being equal to or greater than a refractive index of the light-guide member; and a quantum dot pattern which changes a wavelength of light incident thereto, disposed between the first high-refractive layer and the second high-refractive layer to dispose the first high-refractive layer between the light-guide member and the quantum dot pattern.
