In the 1900s, the cultural crossing of East and West was realized through the acceptance and reproduction of culture. Cultural change in the Orient was the result of attempts to harmonize the West's images, which they chose in their respective countries, with their own culture. However, research on design history until now has been centered on the West, and East was regarded as a beneficiary of civilization inherited from Western's. From the point of view of Western design history as a main trend, the unique characteristics of Korean design culture are not revealed. Therefore, through this studies, we want to distinguish Korea's modern design, which has been recognized as a minority. For the study, through the wallpaper, which is one of the detailed components of the interior space in modern times, we try to analyze the socio - cultural historical factors and design characteristics influencing the formation of the interior space in modern times. Summarizing a result of research. The early modern wallpaper of England mainly uses plants as motifs. But In Korea, animal patterns and letter patterns were used. The reason why European wallpaper was mainly a plant at the time was that the structure of the motif was useful for the process of creation. However, in the case of the Korean wallpaper pattern, the theme was selected according to the meaning of the motif, and it was abstracted appropriately for the 2D design. As a result, many geometric shapes were formed. In addition, European wallpaper pattern is more complex and organic than Korean wallpaper pattern. Therefore, the boundary of the central pattern as the basic unit is unclear and the patterns are connected. The pattern development method is not a simple repetition but a combination of symmetry and repetition. In Korea, on the other hand, the boundaries of unit patterns are clear and patterns are developed by simple repetition. There are many diamond-type repeating patterns in particular.
