Abstract
A display substrate includes a plurality of pixels. Each of the pixels includes a switching element, a storage capacitor, a storage line and a pixel electrode. The switching element includes a polycrystalline silicon layer having a channel portion and a doped portion, a gate electrode, a source electrode and a drain electrode. The gate electrode is formed on the channel portion and has a lower layer and an upper layer. The source electrode and the drain electrode make contact with the doped portion. The storage capacitor includes a first storage electrode formed from a layer substantially same as the polycrystalline silicon layer and a second storage electrode formed from a layer substantially same as the lower layer of the gate electrode.
