1. An electronic device comprising
a housing including a first plate forming an outer face,
wherein the first plate includes:
a glass plate including a first surface outwardly facing the housing and a second surface inwardly facing the housing;
a coating layer including an anti-reflection coating and/or an anti-finger coating above the first surface while forming the outer face;
a color structure layer:
wherein the color structure layer comprising:
a first layer formed between the first surface of the first glass plate and the coating layer, having a first thickness, and including a first inorganic material;
a second layer formed between the first layer and the coating layer, having a second thickness, and including a second inorganic material different from the first inorganic material;
an anti-wear laver formed between the second layer and the coating layer, having a third thickness thicker than each of the first thickness and the second thickness, and including a third inorganic material; and
an opaque layer formed on the second surface.
