A multi-display apparatus includes two panels disposed with a step difference so that pixel boundaries of display devices formed on substrates overlap, and at least one of the two panels includes a thin film encapsulation layer covering the display device and disposed on an adjacent surface of one of the two panels where there is the step difference to improve a disconnection of an image at a seam between the two panels, and mitigate a perspective difference of the image at the seam due to the step difference between the two panels, thereby realizing a large natural and smooth image.
