## Abstract

A flexible display includes: a display panel which is flexible; and a flexible circuit board which is disposed on a side of the display panel and includes an integrated circuit element provided on a surface thereof and an opening portion. The opening portion is in a shape extending in a second direction vertical to a first direction which is parallel to the side of the display panel to which the flexible circuit board is connected, and the integrated circuit element and the opening portion are arranged in the first direction.

## Claims

### Claim 1

A flexible display comprising:
a display panel which is flexible; and
a flexible circuit board which is disposed on a side of the display panel and includes an integrated circuit element provided on a surface thereof, a power source line which supplies a driving current to the display panel, and an opening portion provided on the power source line,
wherein the opening portion is in a shape extending in a second direction vertical to a first direction which is parallel to the side of the display panel, and the integrated circuit element and the opening portion are arranged in the first direction.

### Claim 2 (depends on 1)

The flexible display according to claim 1,
wherein the integrated circuit element is disposed in a region between a straight line which passes through a first end of the opening portion in the second direction and is parallel to the first direction and a straight line which passes through a second end of the opening portion in the second direction and is parallel to the first direction.

### Claim 3 (depends on 1)

The flexible display according to claim 1,
wherein the flexible circuit board includes a plurality of the opening portions, and
the integrated circuit element is disposed between the opening portions.

### Claim 4 (depends on 1)

The flexible display according to claim 1,
wherein a lengthwise direction of the opening portion is parallel to a direction of a current in the power source line.

### Claim 5 (depends on 1)

The flexible display according to claim 1,
wherein the opening portion is in a shape of a slit.

### Claim 6 (depends on 1)

The flexible display according to claim 1,
wherein the opening portion has an inner peripheral surface covered with resin.
