Claim:
1. A display apparatus, comprising: a foldable substrate; a pixel array comprising a plurality of pixels on a central portion of the foldable substrate, a respective pixel comprising an electro-optical device; a resin film on the pixel array; a peripheral circuit on a peripheral portion of the foldable substrate and configured to drive the pixel array; pads on the peripheral portion of the foldable substrate and connected to the peripheral circuit, wherein the peripheral portion of the foldable substrate includes a folding portion, and the pads are provided at a location on the peripheral portion of the foldable substrate, on which the peripheral circuit is provided, farther than the folding portion; and a circuit element formed on the foldable substrate and adapted to configure a circuit section configured to drive the electro-optical device; a flattening film and a window insulation film laminated on the circuit element; and a second substrate disposed above the flattening film and the window insulation film in a region of the foldable substrate other than the peripheral portion of the foldable substrate and the folding portion of the peripheral portion of the foldable substrate, wherein the foldable substrate is folded such that the peripheral portion of the foldable substrate partially overlaps the central portion of the foldable substrate and the peripheral circuit and the pads are under the pixel array, and wherein a groove configured to prevent water invasion is formed in a side of the pixel array and along a side of the peripheral circuit with respect to the folding portion on the foldable substrate in such a manner as to surround the pixel array and the peripheral circuit.
