    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.

    Abstract: Disclosed are an organic light-emitting display device and a method of manufacturing the same. In the organic light-emitting display device, a first protrusion is provided to protrude from a planarization layer, which has a pixel contact hole configured to expose a thin-film transistor disposed on a substrate, toward a cathode electrode of an organic light-emitting element, and a side surface angle of the first protrusion differs from a side surface angle of the planarization layer, which is exposed through the pixel contact hole. Thereby, the cathode electrode and an auxiliary connection electrode may be electrically connected to each other without a separate partition, which may simplify the structure and the manufacturing process of the organic light-emitting display device.

    Abstract: A touch display device exhibiting low reflectivity is disclosed. The touch display device includes a light-blocking stack composed of at least two light-blocking color layers overlapping a plurality of touch electrodes disposed on an encapsulation unit, and a low-reflection layer disposed on the light-blocking stack, thereby absorbing external light without a separate polarizing plate, thus exhibiting low reflectivity.
