Abstract: Embodiments of the disclosure relate to a display device. Specifically, there may be provided a display device in which the planarization layer includes a convex portion, an inclined surface, and a slit portion to effectively extract the light from the display device to the outside to provide enhanced light efficiency, and the lower protection metal is disposed not to overlap the inclined surface to mitigate deterioration of luminance in the direction of the side viewing angle.
