Abstract: A display device including a substrate including a display area for displaying an image and a non-display area provided on a side of the display area and including a bending area bent with respect to an axis parallel to a first direction; a plurality of step portions disposed in the bending area and extending in the first direction; a plurality of bridge electrodes extending in a second direction crossing the first direction in the bending area; and a plurality of pattern portions disposed in the bending area. The step portions are spaced apart from each other, and the pattern portions are disposed between adjacent step portions. The pattern portions are lower than the step portions, and an acute angle of sides of each of the pattern portions from the substrate is smaller than an acute angle of sides of each of the step portions from the substrate.
