Abstract
An organic electroluminescent display (ELD) device includes first and second substrates having a plurality of sub-pixels defined thereon, the first and second substrates being spaced apart from and opposing each other, an array element layer on the first substrate, the array element layer having a plurality of thin film transistors corresponding to each sub-pixel, a first electrode on an inner side of the second substrate, an organic light-emitting layer beneath the first electrode, a second electrode corresponding to each sub-pixel beneath the organic light-emitting layer, a plurality of electrical connecting patterns corresponding to each sub-pixel between the array element layer and the second electrode, the electrical connecting pattern being formed of material having a plastic deformation property, and a seal pattern formed on one of the first and second substrates, wherein a height of the electrical connecting pattern is smaller than an original height of the electrical connecting pattern measured before an attachment of the first and second substrates.
