Organic light-emitting display apparatus |
摘要 |
An organic light-emitting display apparatus may include a substrate; a thin-film transistor (TFT) disposed on the substrate, and having an active layer, a gate electrode, a source electrode and a drain electrode; a signal line formed on the same layer as the source electrode and the drain electrode; a first insulating layer covers the signal line, the source electrode, and the drain electrode; a pixel electrode formed on the first insulating layer, and electrically connected to the TFT; a pixel-defining layer formed on the first insulating layer, includes an opening exposing the pixel electrode; an intermediate layer formed on the pixel electrode, and includes a light-emitting layer; and an opposite electrode formed on the intermediate layer. The intermediate layer is formed on the pixel-defining layer so as to overlap with the signal line. |

1. An organic light-emitting display apparatus, comprising:
a substrate; a thin-film transistor (TFT) which is disposed on the substrate, and which has an active layer and a gate electrode insulated from each other, and a source electrode and a drain electrode electrically connected to each other; a signal line formed on a same layer as the source electrode and the drain electrode; a first insulating layer which covers the signal line, the source electrode and the drain electrode; a pixel electrode which is formed on the first insulating layer, and which is electrically connected to the TFT; a pixel-defining layer which is formed on the first insulating layer, and which comprises an opening exposing the pixel electrode; a first common layer and a second common layer which are commonly formed on the pixel-defining layer and the pixel electrode, the first common layer and the second common layer overlapping the signal line, the first common layer contacting the pixel-defining layer and the pixel electrode; a light-emitting layer interposed between the first common layer and the second common layer, the light-emitting layer formed on the pixel electrode so as to extend on a portion of the pixel-defining layer, the portion overlapping the signal line; and an opposite electrode which is formed on the second common layer. |
