    Abstract: A display device may include a switching composite layer, a first electrode, a pixel defining layer, an emission layer, a second electrode, an encapsulation layer, a light blocking layer, and a touch sensor. The first electrode is positioned on the switching composite layer. The pixel defining layer covers an edge of the first electrode and has a first opening and a second opening that are spaced from each other. The emission layer is positioned inside the first opening. The second electrode covers the switching composite layer, the pixel defining layer, and the emission layer. The encapsulation layer covers the second electrode. The light blocking layer is positioned on the encapsulation layer. The touch sensor is positioned on the light blocking layer and includes a sensing electrode set. A material portion is positioned inside the second opening of the pixel defining layer and overlaps the sensing electrode set.

    Abstract: A display device includes a substrate including a display area and a non-display area surrounding the display area, a light emitting structure disposed on the substrate in the display area, a thin film encapsulation layer disposed on the light emitting structure, an optical structure including a first refractive pattern and a second refractive pattern, and a partition wall disposed on the substrate in the non-display area and surrounding the second refractive pattern. The first refractive pattern is disposed on the thin film encapsulation layer, and overlaps the light emitting structure. The second refractive pattern covers the first refractive pattern, has a refractive index smaller than a refractive index of the first refractive pattern, and includes an organic material.

    Abstract: An organic light-emitting display device including: a substrate; a pixel electrode on the substrate; a pixel defining film on the pixel electrode and having a first opening at least partially exposing the pixel electrode; an organic light-emitting layer on the exposed portion of the pixel electrode; a common electrode on the organic light-emitting layer and the pixel defining film; an encapsulation layer on the common electrode; a black matrix on the encapsulation layer and having a second opening overlapping the first opening; and a plurality of first sensing lines on the black matrix and surrounding the pixel electrode in a plan view to define a pixel region. At least portions of the first sensing lines defining the pixel region do not overlap the common electrode in the pixel region to reduce the common electrode's influence on the touch sensing lines and improve touch sensitivity.
