    Abstract: An ultraviolet curable black ink composition, a bezel pattern forming method using the same, a bezel pattern produced by the method, and a display substrate including the bezel pattern; are disclosed herein. In some embodiments, an ultraviolet curable ink composition includes a black pigment, a dispersant, an epoxy compound, an oxetane compound, a light diffusing agent, a photopolymerization initiator, and an organic solvent. The ultraviolet curable black ink composition is developed to be applied to a cover window film of a foldable display, has excellent light shielding properties and folding properties at a thin thickness, and as a light diffusing agent is applied to the ink, prevents surface wrinkles from generating due to a difference in the curing rate of the upper and power portions of a bezel, by means of UV curing alone without a pretreatment process.

    Abstract: Disclosed is a single-side single-sheet touchscreen, including a substrate; a first conductive pattern, formed in a transverse direction (x-axis) on a surface of the substrate and including at least two pattern columns, each having two or more conductive pattern regions that are electrically connected to each other; a second conductive pattern, formed on the surface of the substrate on which the first conductive pattern is formed and including two or more conductive pattern regions that are not electrically connected to the first conductive pattern and are not electrically connected to each other; a transparent electrode for electrically connecting the conductive pattern regions of the second conductive pattern in a longitudinal direction (y-axis); and a transparent insulation part, disposed between the transparent electrode and the first conductive pattern to electrically insulate the transparent electrode and the first conductive pattern from each other, wherein the transparent insulation part has a blank space at a portion that comes into contact with the second conductive pattern. A method of manufacturing the same is also provided.
