Abstract

According to one embodiment, a display device includes an insulating substrate including a first surface, and a second surface opposite to the first surface, a circuit board mounted on the first surface, a supporting member adhered to the insulating substrate on the second surface, and an antistatic layer located between the insulating substrate and the supporting member.

First claim

What is claimed is:

1. An electronic device comprising:
an insulating substrate comprising a first surface, and a second surface opposite to the first surface;
a circuit board mounted on the first surface;
a supporting member adhered to the insulating substrate on the second surface; and
an antistatic layer located between the insulating substrate and the supporting member,
wherein
a resistance of the antistatic layer is less than a resistance of the insulating substrate.

2. The electronic device of claim 1 , wherein
the antistatic layer is formed of an admixture of resin and conductive inorganic particles.

3. The electronic device of claim 1 , wherein
a thickness of the antistatic layer is less than a thickness of the entire insulating substrate.

4. The electronic device of claim 1 , wherein
a thickness of the antistatic layer is equal to a thickness of the entire insulating substrate.

5. An electronic device comprising:
an insulating substrate comprising a first area, a second area adjacent to the first area, and a third area adjacent to the second area;
a circuit board mounted in the third area of the insulating substrate;
a base provided between the first area of the insulating substrate and the circuit board;
an adhesive layer provided between the circuit board and the base, and between the first area of the insulating substrate and the base; and
a supporting member adhered to the insulating substrate on a side opposite to a side on which the circuit board is mounted, wherein
the insulating substrate is formed of a polyimide substrate containing conductive inorganic particles, and
the second area of the insulating substrate is bent such that the first area of the insulating substrate faces the circuit board.

6. The electronic device of claim 5 , wherein
the insulating substrate comprises a first surface on the side on which the circuit board is mounted, and a second surface on the side on which the supporting member is mounted, and the side on which the second surface is mounted is opposite to the side on which the first surface is mounted, and
an electrical resistance is highest on the first surface side, is lowest on the second surface side, and is gradually increased from the second surface to the first surface.

7. The electronic device of claim 5 , wherein
the supporting member is not provided in the second area.
