Abstract: Disclosed is a display device capable of being manufactured through a simplified process and having improved touch sensitivity. The display device includes an encapsulation unit disposed on a light-emitting element, a touch sensor disposed on the encapsulation unit, and an intermediate layer disposed between the encapsulation unit and the touch sensor. The intermediate layer includes a first intermediate layer, having a dielectric constant that is lower than a dielectric constant of an organic film disposed above or under the intermediate layer, and a second intermediate layer, having greater hardness than the first intermediate layer, whereby touch sensitivity is improved while processing is simplified.

Abstract: Disclosed is an organic light emitting display device with a touch sensor. The display device has a touch sensor that is directly disposed on a sealing part, thus removing the necessity of an additional adhesion process, simplifying a manufacturing process and reducing manufacture cost. In addition, the display device with the touch sensor includes a display cover electrode of a display pad that is made of a same material as a conductive layer included in the touch sensor, thus preventing damage to the display pad electrode.

Abstract: Disclosed are an organic light emitting display device and a method of manufacturing the same to reduce thickness and weight. The organic light emitting display device with a touch sensor removes the necessity of an additional adhesion process by directly forming a touch sensing electrode and a touch driving electrode arranged in parallel and a color filter on an encapsulation layer covering a light emitting device, thereby simplifying a manufacturing process and reducing manufacturing costs.

Abstract: Disclosed is a display device having a reduced non-display area. The display device includes an organic cover layer disposed on an encapsulation unit, an inner dam disposed between a substrate hole and a plurality of light-emitting elements, and a blocking element disposed between the substrate hole and the inner dam, the blocking element being disposed under the organic cover layer, whereby it is possible to prevent damage to a light-emitting stack. In addition, since the substrate hole is disposed in an active area, it is possible to reduce the size of a non-display area.

Abstract: Disclosed are an organic light emitting display having a touch sensor, which may achieve process simplification and cost reduction, and a method of fabricating the same. The organic light emitting display includes a compensation film having a flat surface and formed to cover dams forming a boundary with an organic encapsulation layer and the compensation film has a planarized surface between a region above the dams and a boundary region between the dams and the organic encapsulation layer (144) and may prevent cut and short-circuit of routing lines cutting across the same. Further, touch sensors are disposed on an encapsulation unit including the organic encapsulation layer and thus a separate attachment process is not required, thereby simplifying the overall process and reducing manufacturing costs of the organic light emitting display.

Abstract: Disclosed are a color filter array having a touch sensor and a display panel having the same. The color filter array may comprise: a plurality of color filters arranged in first and second directions on a substrate; a touch block electrode disposed on the color filters to sense a user touch position; a black matrix disposed on the touch block electrode between the color filters; and a touch-sensing line which is disposed in any one of the first and second directions and at least one of which is connected to the touch block electrode. Thereby, when the color filter array is applied to a bending-type or folding-type display device, generation of cracks in the touch sensing line is reduced or minimized.
