Abstract
An organic electroluminescent display device includes: a first substrate having an active area displaying images and a non-active area surrounding the active area; a switching thin film transistor and a driving thin film transistor connected to the switching thin film transistor in the active area on the first substrate; an organic electroluminescent diode connected to the driving thin film transistor; a dummy metal pattern at a corner portion of the non-active area on the first substrate; a second substrate facing and spaced apart from the first substrate, the second substrate including a groove; and a seal pattern attaching the first and second substrates, wherein the dummy metal pattern overlaps a residue at a corner portion of the groove.
