Abstract: 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.

Abstract: A display device may include a substrate including a display area and a non-display area; and a plurality of pixels disposed in the display area, the plurality of pixels each including an emission area and a non-emission area. Each of the plurality of pixels may include at least one light emitting element in the emission area; a first pixel electrode and a second pixel electrode electrically connected to the at least one light emitting element; a bank including a first opening corresponding to the emission area; a color conversion layer disposed in the emission area to correspond to the at least one light emitting element; a barrier layer disposed on the bank and the color conversion layer; and a low refractive layer disposed on the barrier layer. The barrier layer may include silicon oxide (SiOx) having cured polysilazane.
