Disclosed is a method for packaging an organic light emitting display having a reinforcing member between a first substrate and a second substrate by rolling a roll retaining a curable material on non-pixel regions of unit display panels. Organic light emitting pixel arrays are formed at a plurality of pixel regions of a first mother substrate. A frit is formed at a position of a second mother substrate corresponding to the non-pixel regions of the first mother substrate. The mother substrates are coalesced to each other and sealed by the frit. The first and second mother substrates are cut into unit display panels. The unit display panels are aligned. The curable material is coated at a side the unit display panels and cured to form the reinforcing member.
