Abstract
A transflective pixel structure, suitably formed on a substrate, having a scan line formed on the substrate, a gate dielectric layer formed on the substrate and covering the scan line, a data line, formed on the gate dielectric layer, a protection layer formed on a part of the gate dielectric layer and covering the data line, a transparent pixel electrode formed on the protection layer, a reflective pixel electrode formed on the exposed gate dielectric layer, and a double-drain thin-film transistor formed on the substrate. The double-drain thin-film transistor has a gate, a channel layer, a source region and two drain regions. The source region is electrically connected to the data line, the drain regions are coupled to the transparent and reflective pixel electrodes, respectively, and the gate is electrically connected to the scan line.
