1. A display apparatus comprising:
a substrate comprising a display area displaying an image and a peripheral area located around the display area;
a display device located in the display area;
a thin-film encapsulation layer covering the display device and comprising at least one inorganic film and at least one organic film;
a conductive layer located in the peripheral area and surrounding at least a portion of the display area; and
a dam at least partially overlapping an outer edge of the conductive layer,
wherein the dam comprises a center portion, a first inclined portion connected to the center portion and extending from about a top surface of the center portion toward the substrate in a thickness direction of the display apparatus and extending toward the display area in a plan view and at least partially overlapping the conductive layer and a second inclined portion connected to the center portion and extending from about the top surface of the center portion in an opposite direction to the first inclined portion in the plan view,
wherein a shape of the first inclined portion and a shape of the second inclined portion are different from each other,
wherein the first inclined portion meets a surface of the conductive layer at a first angle with respect to the thickness direction and the second inclined portion meets a surface of a layer beneath the second inclined portion at a second angle with respect to the thickness direction;
wherein the first angle and the second angle are with respect to a top surface of the substrate,
wherein the first angle is different than the second angle,
wherein the second inclined portion comprises a recess portion and an adhesion-enhancing portion,
wherein the recess portion is disposed between the center portion and the adhesion-enhancing portion, and the adhesion-enhancing portion is located outside the recess portion from the display area, and
wherein the recess portion has a bottommost portion that has a first height in the thickness direction of the display apparatus that is greater than zero and less than a height of the center portion, and the adhesion-enhancing portion has a second height in the thickness direction of the display apparatus that is equal to or greater than the first height and less than the height of the center portion.
