Abstract: The display device includes a substrate, a transistor, a leveling film, a display element, a partition wall, and at least one dam. The substrate has a display region and a peripheral region surrounding the display region. The transistor is located over the display region. The leveling film is located over the display region and covers the transistor. The display element is located over the leveling film and includes a pixel electrode electrically connected to the transistor. The partition wall covers an edge portion of the pixel electrode. The at least one dam is located over the peripheral region, is spaced away from the leveling film, and surrounds the display region. The at least one dam has a base and stopper. The base includes a material included in at least one of the leveling film and the partition wall.
