Claim 19:
20. A display having an array of pixels, the display comprising:
a substrate;
thin-film transistor structures for the array of pixels, wherein the thin-film transistor structures include a silicon transistor and an oxide transistor, wherein the silicon transistor comprises a polysilicon channel and a first gate, wherein the oxide transistor comprises a semiconducting oxide layer and a second gate;
a light shield that is interposed between the substrate and at least one of the silicon transistor and the oxide transistor;
a buffer layer formed between the substrate and the thin-film transistor structures;
an electrode that is electrically connected to the semiconducting oxide layer; and
at least one dielectric layer that is interposed between the electrode and the semiconducting oxide layer, wherein the at least one dielectric layer comprises a first dielectric layer and a second dielectric layer and wherein a layer of metal is interposed between the first dielectric layer and the second dielectric layer.
