| abstract |
The present invention provides an image display device including a light-emitting layer with high light utilization efficiency and less external light reflection. The image display device of the present invention includes at least a polarizing plate, a refractive index adjustment layer, and a light-emitting layer in this order, and the refractive index of the refractive index adjustment layer is 1.2 or less. In one embodiment, the light-emitting layer is a layer that converts a part of the wavelength of incident light to emit light. In one embodiment, the light-emitting layer includes quantum dots or phosphors as wavelength conversion materials. |
