摘要： A display device includes a light emitting element disposed on a substrate. A color conversion layer is disposed on the light emitting element, the color conversion layer including color conversion particles that convert light of a first color emitted from the light emitting element into light of a second color. An insulating layer is disposed on the color conversion layer. The insulating layer includes a first inorganic layer overlapping the color conversion layer, a second inorganic layer disposed on the first inorganic layer, and a third inorganic layer disposed on the second inorganic layer. A second porosity of the second inorganic layer is greater than a first porosity of the first inorganic layer. A second porosity of the second inorganic layer is greater than a third porosity of the third inorganic layer.
