An organic light-emitting diode (OLED) display and fabrication method for the same are disclosed. In one aspect, the OLED display includes a first substrate including a display area and a non-display area surrounding the display area, wherein the non-display area includes first and second non-display areas and a second substrate formed over the first substrate. The OLED display also includes a dummy electrode formed in the non-display area, an insulating layer formed over the dummy electrode, and a sealant substantially sealing the first and second substrates and formed over the insulating layer in the non-display area. The insulating layer has at least one first through-hole and at least one second through-hole respectively formed in the first and second non-display areas. The sealant is at least partially filled in the first and second through-holes so as to directly contact the dummy electrode.
