Abstract: Disclosed is an electronic device. The electronic device according to various embodiments comprises: a housing; a first glass plate attached to the housing and forming a portion of an external surface of the electronic device, wherein the first glass plate includes a flat portion, a curved portion extending from an edge of the flat portion, a first surface facing outwardly from the electronic device, and a second surface facing inwardly towards the electronic device; and a coating layer formed on the first surface of the first glass plate, wherein the coating layer includes a first layer having a first refractive index and containing at least one first material, and includes a second layer disposed further from the first surface than the first layer, containing at least one second material, and having a second refractive index different from the first refractive index. More specifically, a combination of the first glass plate and the coating layer has a transmittance of 91% to 99%, and with respect to a light having a wavelength of 700 nm to 900 nm, the difference between a minimum reflectance and a maximum reflectance may be 3% or less.
