Abstract

A display structure according to an embodiment may include: a cover glass forming an outer face of the display structure, a display panel disposed under the cover class, a first dielectric layer having a first periphery formed at least in part on an outer side of a periphery of the display panel, and disposed under the display panel, a second dielectric layer disposed on a first face of the first dielectric layer adjacent to the display panel, and a third dielectric layer disposed on a second face corresponding to the first face of the first dielectric layer. A second periphery of the second dielectric layer and a third periphery of the third dielectric layer, corresponding to the first periphery of the first dielectric layer, may be formed on an inner side of the first periphery. The first dielectric layer may have a first permittivity. The second dielectric layer and the third dielectric layer may each have a permittivity greater than the first permittivity.
