Abstract:
1. A display device comprising: a light guide plate; a light source disposed at a lateral side of the light guide plate; a wavelength conversion member to which a light emitted from the light source is incident; and a display panel to which a light emitted from the wavelength conversion member is incident, wherein the wavelength conversion member comprises: a matrix; a plurality of Quantum Dots (QDs) in the matrix; and a protective layer surrounding the matrix, wherein the protective layer comprises ethylene vinylalcohol (EVOH), polyacylonitrile (PAN), polyvinyliden chloride (PVDC), or polyethyleneterephthalate (PET); wherein the wavelength conversion member is interposed between a light emitting diode and the light guide plate; wherein the protective layer has a refractive index with a value between that of the matrix and that of the light guide plate; and wherein the protective layer has a refractive index with a value between that of the matrix and that of a filling material of the light emitting diode.
