## Abstract

According to an aspect, a display device includes: a plate member disposed on a back-surface side of a display unit; a printed circuit board disposed on a back-surface side of the plate member; a flexible printed circuit board that is inserted in a through-hole passing through the plate member and electrically couples the display unit to the printed circuit board; a first tape that is attached to an inside of the through-hole and to a portion of the plate member at a periphery of the through-hole and is disposed between the plate member and the flexible printed circuit board; and a second tape that is attached to the back-surface side of the plate member and to the flexible printed circuit board to close the through-hole. The second tape has a hole through which part of the first tape is exposed.

## Claims

### Claim 1

A display device comprising:
a plate member disposed on a back-surface side of a display unit;
a printed circuit board disposed on a back-surface side of the plate member;
a flexible printed circuit board that is inserted in a through-hole passing through the plate member and electrically couples the display unit to the printed circuit board;
a first tape that is attached to an inside of the through-hole and to a portion of the plate member at a periphery of the through-hole and is disposed between the plate member and the flexible printed circuit board; and
a second tape that is attached to the back-surface side of the plate member and to the flexible printed circuit board to close the through-hole, wherein
the second tape has a hole through which part of the first tape is exposed.

### Claim 2 (depends on 1)

The display device of claim 1, wherein the second tape has two of the holes that are disposed at positions at which the two holes are capable of exposing both edges of the first tape in a width direction of the first tape.

### Claim 3 (depends on 2)

The display device of claim 2, wherein a distance between closest perimeter portions of the two holes is less than a width of the first tape.

### Claim 4 (depends on 3)

The display device of claim 3, wherein a distance between furthest perimeter portions of the two holes is greater than the width of the first tape.
