Abstract
A display device includes: a display panel including a bending area; and a first passivation film and a second passivation film disposed on a first surface of the display panel to be spaced apart from each other. The second passivation film includes a first flat portion and a first stepped portion overlapping the bending area, and a thickness of the first stepped portion is less than a thickness of the first flat portion.
Claims20
A display device comprising:
- a display panel including a first flat area, a second flat area, and a bending area between the first flat area and the second flat area;
- and
- a first passivation film and a second passivation film, which are disposed on a first surface of the display panel to be spaced apart from each other,
- wherein the first passivation film overlaps the first flat area and the second passivation film overlaps the second flat area,
- the first passivation film has a first end portion overlapping the bending area, and the second passivation film has a second end portion overlapping the bending area and spaced apart from the first end portion,
- the first end portion and the second end portion are asymmetric with each other with respective to an imaginary line vertically crossing a center of a space therebetween in a cross-sectional view,
- the second passivation film includes a first flat portion overlapping the second flat area and a first stepped portion overlapping the bending area, and
- a thickness of the first stepped portion is less than a thickness of the first flat portion.
