US Patent 7671368 Capacitor and light emitting display using the same

A capacitor including a polysilicon layer doped with impurities to be conductive, a first dielectric layer formed on the polysilicon layer, a first conductive layer formed on the first dielectric layer, a second dielectric layer formed on the first conductive layer, and a second conductive layer formed on the first dielectric layer. The second conductive layer is coupled to the polysilicon layer.
