A display system which enables a stereoscopic image to be perceived by the naked eye is provided. The display system includes a display panel which can display a first image, a second image, a third image, and a fourth image. The first image has a region overlapping with the third image. The second image has a region overlapping with the fourth image. The first image and the third image are perceived by one of the right and left eyes and the second image and the fourth image are perceived by the other of the right and left eyes, so that a composite image of the first to fourth images is stereoscopically perceivable.
