In a display apparatus, an interface unit receives N image signal groups each including i×j image signals from an external video system, wherein N is a natural number equal to or greater than 2. A display panel includes data lines, gate lines, and pixels to display images. The display panel includes N display areas each having a resolution of i×j, and the N display areas are extended along a vertical direction and sequentially arranged along a horizontal direction. The N display areas display the images corresponding to the N image signal groups input through the N interface units, respectively. Thus, although the display apparatus has an ultra high-definition resolution, a frequency for transmission of the image signals may be prevented from being increased, so that no additional memories are required.
