THIN-FILM TRANSISTOR ARRAY SUBSTRATE AND ORGANIC LIGHT-EMITTING DISPLAY INCLUDING THE SAME |
| 摘要 |
A thin-film transistor (TFT) array substrate includes a substrate, a gate-underlying stepped layer disposed on the substrate, a gate electrode disposed on the gate-underlying stepped layer, a semiconductor layer formed over the gate electrode, and an etch-stopper disposed on the semiconductor layer. The gate-underlying stepped layer is formed under the gate electrode and has a width greater than a width of the gate electrode. |
