Abstract: Signal lines are formed to cover semiconductor layers around gate electrodes of pixel switching elements thereby to shield the switching elements. The semiconductor layers connected to drain electrodes of the switching elements extend under the signal lines. Storage capacitor lines also extend along the signal lines. Storage capacitors are defined between the semiconductor layers and the storage capacitor lines. The storage capacitor lines divide the pixel electrodes into first and second regions, respectively. The first and regions are overlapped at least in part with the signal lines. Contacts between the semiconductor layers and the pixel electrodes are disposed apart from the gate electrodes.
