The present invention relates to a display device, a multi-display system including the same and a controlling method thereof. The display device comprises: a first image processing part for processing first image signals; a second image processing part for processing second image signals; a display part for displaying a first image corresponding to the first image signals as a main screen and a second image corresponding to the second image signals as a Picture in Picture (PIP) screen having a preset size at least with a partial region overlapping with the first image; a communication part for communicating with the outside; and a control part for controlling the display part to display the PIP screen after moving the PIP screen at a preset speed and in a preset direction based on the setting information of the PIP screen and controlling the communication part to conduct either or both of transmission and reception of the motion information of the PIP screen with respect to an adjacent and external second display device. Accordingly, the effect of continuously operating the PIP screen can be generated as the motion information of the PIP screen is shared. |
