A transflective pixel structure including a scan line, a data line, a thin film transistor, a pixel electrode and an organic material layer is provided. The scan line and the data line are disposed over a substrate. The thin film transistor is disposed over the substrate and electrically connected to the scan line and the data line. The pixel electrode is disposed over a substrate and is electrically connected to the thin film transistor. The pixel electrode has a reflective region and a transmissive region. The organic material layer covers both the thin film transistor and the pixel electrode. The organic material layer disposed correspondently above the transmissive region of the pixel electrode has a plurality of refracting patterns on its upper surface. The refracting patterns refract external light into the reflective region.
