Abstract: Provided are a display device and a method of manufacturing a display device. The display device includes a first substrate in which a display area and a non-display area disposed outside the display area are defined; a second substrate which faces the first substrate and comprises an area recessed in a thickness direction and a contact area disposed outside the recessed area; and a cell seal which bonds the first substrate and the second substrate together, wherein the cell seal comprises a bonding filament which is disposed between the contact area and the non-display area to connect the contact area and the first substrate and a frit seal which is disposed between the recessed area and the non-display area.
