Regarding claim 2. SEO disclose the display device according to claim 1, SEO further disclose wherein a top surface of the lower alignment key (Fig. [6-7], touch panel 150, interpreted as alignment key, Para [ 0082]) is in contact with a bottom surface of the dam (Fig. [6-7], dam member 700, Para [ 0059]), and a bottom surface of the lower alignment key (Fig. [6-7], touch panel 150, interpreted as alignment key, Para [ 0082]) is in contact with a top surface of the substrate (Fig. [6-7], first substrate 110, Para [ 0070]). Regarding claim 3.

Regarding claim 4. SEO disclose the display device according to claim 3, SEO further disclose wherein a side surface of the substrate (Fig. [6-7], first substrate 110, Para [ 0070]) and a side surface of the sealing substrate (Fig. [6-7], window body 310, Para [ 0086]) are disposed on the same plane with the side surface of the dam (Fig. [6-7], dam member 700, Para [ 0059]) and the side surface of the lower alignment key (Fig. [6-7], touch panel 150, interpreted as alignment key, Para [ 0082]). Regarding claim 16. SEO disclose the display device according to claim 1, SEO further disclose wherein a side surface of the lower alignment key is exposed (Fig. [6-7], touch panel 150, interpreted as alignment key, Para [ 0082]).

Allowable Subject Matter Claims 8-15 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The following is the Examiner's Reasons for Allowance: The prior art fails to disclose and would not have rendered obvious: Regarding claim 8. a pad part disposed on one side of the non-active area, wherein the dam includes a first dam disposed in the non- active area between the active area and the pad part, and a second dam connected to one side and the other side of the first dam and surrounding the active area.
