Description

This application is a continuation application, claiming priority under § 365(c), of International Application No. PCT/KR2024/007891, filed on Jun. 10, 2024, which is based on and claims the benefit of Korean patent application number 10-2023-0086009, filed on Jul. 3, 2023, and Korean patent application number 10-2023-0134546, filed on Oct. 10, 2023, the disclosures of which are incorporated by reference herein in their entireties. BACKGROUND Field An embodiment disclosed herein relates to a housing and an electronic device including the same. Description of the Related Art Thanks to remarkable advancements in information and communication technology and semiconductor technology, the distribution and use of various electronic devices are rapidly increasing. In particular, recent electronic devices are being developed to be portable and capable of communication. The term “electronic device” may refer to a device that performs a specific function according to an installed program, such as a home appliance, an electronic notebook, a portable multimedia player, a mobile communication terminal, a tablet PC, an image/audio device, a desktop/laptop computer, or a vehicle navigation system. For example, such electronic devices may output stored information as sound or images. As the integration level of electronic devices increases and ultra-high-speed, large-capacity wireless communication becomes widespread, various functions may be incorporated into a single electronic device such as a mobile communication terminal. For example, in addition to communication functions, functions such as entertainment functions like games, multimedia functions like music/video playback, communication and security functions for mobile banking, and functions like scheduling or an electronic wallet are being incorporated into a single electronic device. Such electronic devices are being miniaturized such that a user can conveniently carry them. As the carrying and use of miniaturized or thinned mobile devices, such as smartphones, becomes commonplace, user demands for the exterior design of mobile devices may become more sophisticated and diversified. The above-described information may be provided as related art for the purpose of aiding understanding of the disclosure. No claim or determination is made as to whether any of the foregoing constitutes prior art related to the disclosure. SUMMARY According to an embodiment of the disclosure, in an electronic device including a housing, the housing may include a substrate, a color layer disposed above the substrate, wherein a first material having a first refractive index and a second material having a second refractive index greater than the first refractive index are alternately stacked, a first support layer disposed on the color layer, and a reflective layer disposed on the first support layer, wherein a third material having a third refractive index and a fourth material having a fourth refractive index greater than the third refractive index are alternately stacked. A difference between the first refractive index and the second refractive index may be greater than a difference between the third refractive index and the fourth refractive index. The third refractive index may be greater than the first refractive index. According to an embodiment of the disclosure, in an electronic device including a housing, the housing may include a substrate, a color layer disposed above the substrate, wherein a first material having a first refractive index and a second material having a second refractive index greater than the first refractive index are alternately stacked, a first support layer disposed on the color layer, and a reflective layer disposed on the first support layer, wherein a third material having a third refractive index and a fourth material having a fourth refractive index greater than the third refractive index are alternately stacked. A color coordinate value of the color layer may be 5 or more. A reflectance of the reflective layer may be 10% or greater.
