Abstract

Disclosed herein is a display apparatus, including: a foldable substrate; a pixel array section including a plurality of pixels disposed on the substrate and each including an electro-optical device; the foldable substrate being folded at a substrate end portion at least on one side thereof around the pixel array section; a peripheral circuit section disposed on the substrate end portion and adapted to drive the pixels of the pixel array section; and a pad section provided on the substrate end portion on which the peripheral circuit section is provided and adapted to electrically connect the peripheral circuit section to the outside of the substrate.

First claim

What is claimed is:

1. A display apparatus, comprising:
a foldable first substrate;
a pixel array including a plurality of pixels on a central portion of the first substrate, respective ones of the plurality of pixels comprising an electro-optical device;
a resin film on the pixel array;
a peripheral circuit formed outside of the pixel array and configured to drive the pixel array;
pads on a peripheral portion of the first substrate and connected to the peripheral circuit;
a circuit section configured to drive the electro-optical device and including a circuit element formed on the first substrate;
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 central portion of the first substrate,
wherein the first substrate is folded such that the peripheral circuit partially overlaps the central portion of the first substrate and the peripheral circuit is disposed under the pixel array.

2. The display apparatus according to claim 1 , wherein
the first substrate is folded such that the pads are disposed under the pixel array.

3. The display apparatus according to claim 1 , wherein
the pads are provided at a location on the peripheral portion of the first substrate, on which the peripheral circuit is provided, farther than a folding portion.

4. The display apparatus according to claim 3 , wherein
a groove configured to prevent water invasion is formed on a side of the pixel array with respect to the folding portion on the first substrate in such a manner as to surround the pixel array.

5. The display apparatus according to claim 4 , wherein
the groove is formed along a side of the peripheral circuit with respect to the folding portion in such a manner as to surround the peripheral circuit.
