像素结构
摘要：
本发明公开了一种像素结构，包含基板、栅极、电容电极、第一绝缘层、主动层、漏极以及源极以及延伸电极。栅极设置基板上。电容电极设置于基板上，并与栅极分离。第一绝缘层，覆盖栅极与电容电极，其中第一绝缘层具有凹陷，凹陷位于电容电极的正上方。主动层设置于第一绝缘层上。漏极以及源极设置于主动层上且彼此分隔。延伸电极从漏极或源极延伸入凹陷中。此凹陷能够缩短延伸电极与电容电极的距离，从而增加储存电容的值。由于馈通电压与储存电容值成负相关，故储存电容值的增加能够助于降低馈通电压。
摘要（英）：

The invention discloses a pixel structure comprising a substrate, a grid electrode, a capacitor electrode, a first insulation layer, an active layer, a drain electrode, a source electrode and an extension electrode; the grid electrode is arranged on the substrate; the capacitor electrode is arranged on the substrate, and separated from the grid electrode; the first insulation layer covers the gridelectrode and the capacitor electrode, and has a recess right above the capacitor electrode; the active layer is arranged on the first insulation layer; the drain electrode and the source electrode are arranged on the active layer and mutually separated from each other; the extension electrode extends into the recess from the drain electrode or the source electrode; the recess can shorten the distance between the extension electrode and the capacitor electrode, thus increasing the storage capacitance value; a feedthrough voltage and the storage capacitance value are in negative correlation, so the increase of the storage capacitance value can assist to reduce the feedthrough voltage.
