    Abstract: A display device may include: a substrate including a display area including a pixel area, and a non-display area including a pad area and located at at least one side of the display area; a pixel in the pixel area, the pixel including an emission area in which at least one light emitting element is located, and a non-emission area adjacent to the emission area; a pad in the pad area, the pad being electrically connected to the pixel; a first layer on the light emitting element at the pixel area; and a second layer in the pixel area and the pad area, the second layer including a pad opening formed exposing at least a portion of the pad. The first layer may include an organic layer including a hollow particle. The first layer may be spaced from the pad opening and covered with the second layer.

    Abstract: A display device includes a display area including a first light-emitting area and a second light-emitting area; a peripheral area adjacent to the display area; pixels which emit incident light; an encapsulation layer covering the pixels; a first color-converting pattern corresponding to the first light-emitting area and having a refractivity; a transmission pattern corresponding to the second light-emitting area and through which the incident light is transmitted; a low refractivity layer is in the display area and facing the encapsulation layer with each of the first color-converting pattern and the transmission pattern therebetween, the low refractivity layer including: a resin and a hollow particle which define a refractivity lower than the refractivity of the first color-converting pattern; and a first dam structure in the peripheral area and spaced apart from the display area, the first dam structure and the transmission pattern being portions of a same material layer.

    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.
