PIXEL UNIT AND METHOD OF FABRICATING THE SAME, ARRAY SUBSTRATE AND DISPLAY DEVICE |
| 摘要 |
The present invention provides a pixel unit including a thin film transistor and a pixel electrode, the thin film transistor includes a gate, a source and a drain, and the pixel electrode is electrically connected to the drain through a via hole. An upper end surface of the via hole is connected to the pixel electrode, and a lower end surface of the via hole is connected to the drain. The via hole is a step-shaped hole, and an area of the upper end surface of the via hole is larger than that of the lower end surface of the via hole. The present invention also provides a method of fabricating the pixel unit, an array substrate including the pixel unit, and a display device including the array substrate. |
