An organic electroluminescence display panel comprises a first substrate, a second substrate assembled to the first substrate, an organic light-emitting layer positioned between the first and second substrates, a sealant positioned between the first and second substrates, a varying pattern zone, and supplemental pattern zone. The second substrate comprises a sealant dispensing area, a metal region, and a non-metal region adjacent to the metal region. The metal region includes plural traces. The sealant is formed in the sealant dispensing area of the second substrate. The varying pattern zone is formed at one of the traces of the metal region, and is corresponding to the sealant dispensing area. The varying pattern zone comprises plural conductive portions. The supplemental pattern zone comprising plural supplemental conductive portions is formed at the non-metal region. A width of the conductive portions is larger than a width of the supplemental conductive portions.
