Abstract

A display substrate according to an embodiment relates to a display substrate including a display panel mounting area and a bezel area. The display substrate includes one surface and another surface opposite to the one surface, and includes: a first region defined as a folded region; and a second area defined as an expanded area in which a groove is formed on one surface or the other surface of the display substrate, and the groove is formed in a display panel mounting area of the first area, and a hole is formed through the one surface and the other surface of the display substrate, and the hole is formed in a bezel area of the first area.

Description

technical field [0001] Embodiments relate to a display substrate and a display device including the display substrate. Background technique [0002] Recently, there is an increasing demand for flexible or foldable display devices that can easily carry various applications and display images on a large screen while being carried. [0003] Such a flexible or foldable display device is folded or partially bent when carried or stored, and can be implemented as an unfolded display when displaying an image. Therefore, an image display area can be increased, and a user can easily carry the display. [0004] After the flexible or foldable display device is folded or bent, the recovery process of unfolding the flexible display device again may be repeated. [0005] That is, since the flexible or foldable display device repeats folding and unfolding operations, the substrate of the flexible or foldable display device is required to have a certain strength and elasticity, and no crac...
