Glass substrate and display device comprising the same

A method for reducing warp in a thin film device, comprising applying at least one metal film to a convex surface of a glass substrate, wherein the glass substrate is a substantially dome-shaped or bowl-shaped.

A thin film device comprising a glass substrate and at least one metal film disposed on a surface of the glass substrate,

• wherein the metal film has at least one dimension chosen from a thickness ranging from about 1,000 Å to about 10,000 Å or a width ranging from about 1,000 Å to about 10,000 Å;
• and
• wherein the warp of the thin film device is less than about 1000 microns.

A thin film device comprising a glass substrate and at least one metal film disposed on a surface of the glass substrate,

• wherein the glass substrate has a substantially constant thickness over a length and width of the substrate, and
• wherein the warp of the thin film device is less than about 1000 microns.

A method of forming a thin film device comprising:

• supporting a glass sheet having a thickness between 0.2 mm and about 1.0 mm comprising a concavity on a flat reference surface in an orientation such that the glass sheet is dome shaped relative to the flat reference surface;
• and
• depositing a thin film material on a dome side of the glass sheet.

A thin film device comprising a glass sheet having a concavity, wherein the thin film device is disposed on a dome side of the glass sheet when the glass sheet is supported on a flat reference surface and wherein the glass sheet has a thickness between 0.2 mm and about 1.0 mm.
