Abstract: A display that includes a display panel and a window laminated with the display panel is presented. The display panel may include: a main panel region including a first side extending in a first direction and a second side extending in a second direction crossing the first direction; a first sub-panel region that is in contact with the first side and is bent; and a second sub-panel region that is in contact with the second side and is bent. A panel corner part of the main panel region adjacent to the first sub-panel region and the second sub-panel region is rounded.
