Classification: CPC H  G | IPC G  H

Claim 15:
16. A display comprising:
a substrate;
a buffer layer formed over the substrate;
thin-film transistor structures, wherein the buffer layer is interposed between the substrate and the thin-film transistor structures, 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 polysilicon channel is interposed between the buffer layer and the first gate, wherein the oxide transistor comprises a semiconducting oxide layer and a second gate, and wherein the semiconducting oxide layer is interposed between the buffer layer and the second gate; and
a light shield that is interposed between the substrate and the buffer layer, wherein the light shield overlaps at least one of the silicon transistor and the oxide transistor.
