3T pixel structure and related liquid crystal display

摘要

A 3T pixel structure is provided. The 3T pixel structure includes: a substrate, on which a lower common electrode and a scan line are positioned; a first dielectric layer, positioned on the lower common electrode, the scan line and the substrate; a charge-sharing thin film transistor (TFT), including a source, a drain, and a gate, the source and the drain of the charge-sharing TFT being positioned on the first dielectric layer; a data line, positioned on the first dielectric layer; a second dielectric layer, positioned on the source, the drain, the data line of the charge-sharing TFT and the first dielectric layer; and an upper common electrode, positioned on the second dielectric layer. The second dielectric layer has a source hole to allow the upper common electric layer to contact the first source and electrically connect to the first source through the source hole.
