Abstract: Embodiments of the invention provide a composite powder including a core layer disposed at the center thereof and formed of a reflecting material, a first coating layer formed on a surface of the core layer, and a second coating layer formed on a surface of the first coating layer and having a refractive index higher than that of the first coating layer. According to at least one embodiment, high whiteness is more effectively implemented through a bezel in a thin film shape by forming a bezel layer and a reflecting layer of a touch sensor.

Abstract: Embodiments of the invention provide a touch sensor including a substrate, and an electrode on the substrate. The electrode includes a first diffusion barrier contacting the substrate, an intermediate layer formed on the first diffusion barrier, and a second diffusion barrier formed on the intermediate layer. According to an embodiment of the invention, corrosion of the intermediate layer and performance degradation caused by diffusion may be prevented by forming the intermediate layer on the first diffusion barrier contacting the substrate and forming the second diffusion barrier on the intermediate layer.

Abstract: Disclosed herein is provided with a touch sensor, including: a window substrate; a first bezel layer formed at an edge portion of the window substrate and formed of at least one layer; and a resin layer disposed on the first bezel layer and the window substrate. The touch sensor further includes a second bezel layer disposed on the resin layer, at a position corresponding to the first bezel layer and the resin layer is made of a transparent material having a refractive index lower than that of the first bezel layer and the second bezel layer. As described above, the plurality of bezel layers and the resin layer are stacked together to form a difference in refractive index, thereby implementing a clear color even by the thinner bezel layer.

Abstract: Embodiments of the invention provide a touch sensor, including a window substrate, and bezel layers formed along an outer circumference on the window substrate. The bezel layer includes a photochromic compound or a thermochromic compound expressing at least two colors.
