Abstract: The present specification relates to a display device in which reliability can be secured and a narrow bezel can be implemented by removing a structure of a dam, such as an engraved dam or an embossed dam, from a bezel area of the display device. To achieve this, in the display device according to the present specification, by forming a surrounding through hole in the form of surrounding an active area to pass through a display panel in a bezel area of the display panel and when a particle cover layer is formed in a manufacturing process, radiating ultraviolet light through the surrounding through hole of the bezel area to cure the particle cover layer, it is possible to remove a structure of a dam, thereby preventing the occurrence of defects in the bezel area.
