Abstract:
1. An organic electroluminescence display comprising: a substrate; a gate line disposed on the substrate and extending in a first direction; a data line disposed on the substrate and extending in a second direction substantially perpendicular to the first direction, the gate line and data line overlapping in a crossing region; a first thin-film transistor (TFT) electrically connected to the gate line and the data line, comprising a gate electrode, an active layer that comprises an oxide semiconductor, a source electrode, a drain electrode, and a gate insulating layer interposed between the gate electrode and the active layer; a capacitor electrically connected to the first TFT and comprising a lower electrode comprising the same material as the gate electrode, and an upper electrode; a insulating layer interposed between the lower electrode and the upper electrode; a second TFT electrically connected to the capacitor; an organic light-emitting diode (OLED) electrically connected to the second TFT; a semiconductor island disposed in the crossing region and separated from the active layer, the semiconductor island comprising the oxide semiconductor; and an insulating island disposed in the crossing region, between the semiconductor island and the gate line, and comprising the same typo of material as the gate insulating layer, wherein the insulating island and the semiconductor island have the same size and shape.
