Abstract
An organic electroluminescent display ('OELD') includes an organic light-emitting diode ('OLED'), a circuit region, and an interlayer dielectric (“ILD”) layer. The OLED is disposed in each of a plurality of pixels arranged on a substrate. The circuit region includes two or more thin film transistors (“TFTs”) and a storage capacitor. The ILD layer has two or more insulating layers and includes a first region disposed between both electrodes of the storage capacitor and a second region covering the TFTs. At least one of the insulating layers has a window exposing the insulating layer directly beneath the at least one insulating layer so that that the ILD layer is thinner in the first region than in the second region. Accordingly, it is possible to reduce an occupation area of the storage capacitor while maintaining the necessary capacitance of the storage capacitor and expanding the area of the luminescent region.
