Abstract: A display device is disclosed, which may prevent an inorganic film formed in an organic film open area from being damaged and prevent a cathode electrode from being shorted. The display device includes a substrate including a display area on which pixels area arranged, and a non-display area surrounding the display area; a first metal layer formed in the non-display area of the substrate; at least one insulating film arranged on the first metal layer; a second metal layer arranged on the at least one insulating film and connected with the first metal layer through a contact hole that passes through the at least one insulating film formed in the non-display area; a cover layer arranged on the contact hole and formed to overlap the contact hole; and an encapsulation film formed to cover the display area and the cover layer.

Abstract: A flexible display device can include a first portion in which an organic light emitting element is disposed on a first surface; a base layer made of a flexible substrate including a second portion, outside of the first portion, having a bend section bent toward a second surface opposite to the first surface; and a protective coating layer covering at least a part of the second portion, wherein a polarization layer is on the organic light emitting element of the first portion without a barrier film, and wherein the protective coating layer is coated such that a portion adjacent to the polarization layer is thicker than the other portion.
