Claim 8:
9. A display device comprising:
a substrate having a display region and a peripheral region surrounding the display region;
a transistor over the display region;
a leveling film over the display region, the leveling film covering the transistor;
a light-emitting element over the leveling film, the light-emitting element including a pixel electrode electrically connected to the transistor;
a partition wall covering an edge portion of the pixel electrode;
at least one dam over the peripheral region, the at least one dam being spaced away from the leveling film and surrounding the display region; and
a supplemental dam over the peripheral region, wherein
the at least one dam is sandwiched by the leveling film and the supplemental dam,
the at least one dam comprises:
a base including a material included in at least one of the leveling film and the partition wall; and
a stopper over and in contact with the base, the stopper including an inorganic compound,

a part of the upper surface of the at least one dam is exposed from the stopper, and
the base comprises:
a first layer including a first organic compound included in the leveling film; and
a second layer over the first layer and in contact with the first layer and the stopper, the second layer including a second organic compound included in the partition wall.
