Abstract: A display device includes a first substrate having a thin-film transistor; a second substrate spaced apart from the first substrate; a dam disposed between the first substrate and the second substrate and disposed on an edge area of the first substrate; and a gap-maintaining film disposed between the first substrate and the second substrate and disposed on a central area of the first substrate surrounded with the edge area, wherein the dam contains an UV curable resin and a curing retarder. Thus, a sufficient time duration required for a bonding process after UV irradiation for curing the dam is secured.
