Abstract: A display device according to embodiments of the present disclosure includes at least one groove formed in an organic file disposed on a substrate. As a result, it is possible to discharge, or delay the movement of, moisture generated in a manufacturing process of the display device, or gas remaining in an organic film. Thus the display quality and lifetime of the display device can be improved.
