Claim:
1. A display device, comprising: a first base substrate; a thin film transistor disposed on the first base substrate that includes a semiconductor layer, a gate electrode, a source electrode, and a drain electrode; a first passivation layer that covers the thin film transistor and that includes an inorganic insulating material; a second passivation layer disposed on the first passivation layer that includes an exposure hole exposing the first passivation layer on the drain electrode; a common electrode disposed on the second passivation layer; a third passivation layer that covers the common electrode and that includes a contact hole disposed inside the exposure hole exposing the drain electrode; a cavity between the first passivation layer and the third passivation layer on the drain electrode; and a pixel electrode disposed on the third passivation layer and connected with the drain electrode.
