1. An electronic device, comprising:
a housing;
a front plate disposed on one surface of the housing; and
a rear plate disposed on a rear surface of the housing,
wherein at least one of the front plate and the rear plate includes:
a transparent plate configured to at least partially transmit light,
a base film attached to one surface of the transparent plate and configured to at least partially transmit light,
an ultra-violet (UV) molding layer formed on a surface of the base film,
a plurality of refractive layers sequentially stacked on a surface of the UV molding layer, and
a light-blocking layer stacked on a terminal layer of the plurality of refractive layers, and
wherein, the plurality of refractive layers include:
a first plurality of refractive layers sequentially stacked on a surface of the UV molding layer, and
a second plurality of refractive layers disposed at regular intervals or irregular intervals between the light-blocking layer and a terminal layer of the first plurality of refractive layers, and
wherein at least one of the plurality of refractive layers is formed to have a different refractive index and each of the second plurality of refractive layers is formed to have a surface area smaller than a surface area of each of the first plurality of refractive layers.
