Abstract: In a multi-display device, first and second panels, each of which has a display device, are stuck fast to each other to embody a screen. The first panel has an interface surface formed of a hard material, and the second panel has an interface surface formed of a soft material. Thus, the soft material is elastically compressed and transformed by the hard material so that the two panels are closely in contact with each other, and formation of air gaps is prevented at the joint between the panels. As a result, image cutting in a screen due to a luminance difference can be minimized so that an image can be naturally connected between the two panels.
