[Prior Art] The surface of the housing of the portable electronic device is usually provided with a two-dimensional planar pattern for decoration, and the two-dimensional planar pattern is formed by printing or spraying. Since the two-dimensional planar pattern does not have a three-dimensional effect, it is difficult to satisfy the consumer's requirement for the stereoscopic feeling of the decorative pattern of the casing. In order to provide a three-dimensional effect to the decorative pattern of the casing, a conventional method has a three-dimensional graphic display technique in which a pattern is formed on the body using a clock-injection holography technique. However, the pattern formed by laser holography is relatively simple and costly. Another method is to use a pad printing technique to form a multi-layered pattern on the casing. A pattern is formed between each of the pattern layers and the other pattern layers by a transparent film, thereby forming a multi-layer effect in which the multi-layer pattern is superimposed. However, the multilayer structure of the multi-layered pattern is complicated, so that it requires a large number of processes in industrial production, and thus, the manufacturing of the casing takes a long time and costs.
