Display device

摘要

The present invention provides a display device having excellent light energy conversion efficiency. The present invention relates to a display device including a light-diffusing layered body. The light-diffusing layered body includes a wavelength conversion layer containing optically isotropic semiconductor particles and a light-diffusing layer on at least one surface of the wavelength conversion layer. The light-diffusing layer contains a binder component and light-diffusing particles that contain an organic material or an inorganic material. The light-diffusing particles protrude in a range of 3 to 50% of the particle size of the light-diffusing particles from an outermost surface of the light-diffusing layer. The light-diffusing layer has projections and depressions on the outermost surface due to the light-diffusing particles protruding therefrom. The light-diffusing layer has a film thickness of 1 to 30 μm.
