Disclosed is a method for packaging an organic light emitting display having a reinforcing member formed between a first substrate and a second substrate by dipping non-pixel regions of unit display panels in a liquid curable material. 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 the second mother substrate corresponding to non-pixel regions of the first mother substrate. The first and second mother substrates are coalesced to each other and sealed by the frit. The mother substrates are cut into unit display panels. The unit display panels are aligned. Non-pixel regions of the unit display panels are dipped in the liquid curable material and the material is cured to form the reinforcing member.
