Disclosed are an organic light emitting display device and a method of making the same. A first mother substrate includes a first display array and a second display array. A second mother substrate is attached to the first mother substrate in order to seal the arrays. A frit is formed at non-pixel regions of the first mother substrate and the second mother substrate. The frit interconnects the first and second mother substrates to each other. A reinforcing member is formed along the frit. A metal pattern is formed on the first substrate and extends along the reinforcing member.
