To provide a display position display device that arranges components according to the environment of an interface without increasing a capacity of use in a storage device.

A language system used as the environment of an interface is acquired first from an external memory (S101). For example, English and Japanese are language systems, in which characters are written from a left side to a right side, so in this case (S102: English), position information on components is used as it is to arrange them on the screen of a display device (S104). When a language system is Arabic (S102: Arabic), on the other hand, characters are written from a right side to a left side, so X coordinates of the same position information are recalculated (S107), and components are arranged and displayed at positions on the right-left opposite side from those of English (S108).
