Back plane for flat panel display and method of manufacturing the same

A method of manufacturing a back plane for a flat panel display, the method comprising:

• forming a first capacitor and a gate electrode on a substrate, the first capacitor comprising a first electrode, an insulation pattern layer on the first electrode, and a second electrode on the insulation pattern layer;
• forming a first insulation layer on the substrate and covering the first capacitor and the gate electrode, the first insulation layer contacting the first electrode, the insulation pattern layer, and the second electrode;
• forming an active layer on the first insulation layer to correspond to the gate electrode;
• forming a second insulation layer, which covers the active layer while providing first and second holes for exposing a portion of the active layer, on the first insulation layer;
• and
• forming a source electrode and a drain electrode on the substrate to contact a portion of the active layer,
• wherein the gate electrode and the first capacitor are formed at the same layer, the first electrode comprises a same material as the gate electrode, and the insulation pattern layer comprises different material from the gate electrode.
