Abstract

A display device according to an embodiment includes: a substrate including a first region, a second region, and a bending region between the first region and the second region; a display unit that overlaps the first region; and a protective layer overlapping the bending region, the substrate including a groove located in the bending region, and at least one of angles formed by a side wall of the groove and an upper surface of the substrate being 90 degrees or less.

Description

technical field [0001] The present disclosure relates to display devices. Background technique [0002] As the use of various display devices such as mobile phones, tablet PCs, notebook computers, display screens for computers, and TVs increases, the demand for quality improvement of the display devices also increases. [0003] In the case of a display device, there is also a demand for improvement in the performance of the screen such as the resolution of the screen, quality such as the performance of reducing power consumption, and in the case of a portable electronic device, it is necessary to reduce the weight so that it can be easily moved and ensured. Visibility so that the screen can be displayed smoothly externally is also an important object of quality improvement. [0004] On the other hand, efforts are also being made to reduce the peripheral area corresponding to the area other than the display area in the screen portion of the display device so that an image ca...
