Abstract: An organic light-emitting diode (OLED) display apparatus is provided. The OLED display apparatus includes a substrate, an initialization voltage line, a first thin film transistor (TFT) including an active layer. The initialization voltage line transmits an initialization voltage. The first thin film transistor (TFT) includes an active layer, a gate electrode, and an auxiliary gate electrode. The active layer is disposed on the substrate and includes a source region, a channel region, and a drain region. The gate electrode is disposed on the channel region. The auxiliary gate electrode is disposed on the gate electrode on a boundary between the channel region and the drain region. The voltage application electrode is disposed on the auxiliary gate electrode and is connected to the initialization voltage line and the auxiliary gate electrode.

Abstract: An organic light-emitting diode (OLED) display is disclosed. In one aspect, the OLED display includes a substrate, an interlayer insulating layer arranged over the substrate and an OLED arranged over the interlayer insulating layer. The OLED display also includes a source electrode and a drain electrode arranged over the interlayer insulating layer and a via layer arranged over the interlayer insulating layer and having a via hole exposing the source electrode or the drain electrode. The interlayer insulating layer includes a projecting portion which projects toward the OLED in the via hole.
