## Abstract

A display panel provided with a protective film includes a display panel and the protective film that is provided on a display surface of the display panel, in which the display panel is provided with a first through-hole passing through the display panel in a thickness direction, the protective film includes a first protective film, the first protective film is provided with a second through-hole passing through the first protective film in the thickness direction, the first through-hole and the second through-hole are in communication with each other and form a through-hole, the first protective film includes a first grip portion at a peripheral edge portion of the first protective film, and the first protective film includes a dividing portion that continues from the second through-hole to an end side of the first grip portion.

## Claims

### Claim 1

A display panel provided with a protective film, comprising:
a display panel; and
the protective film that is provided on a polarizer surface of the display panel, wherein
the display panel is provided with a first through-hole passing through the display panel in a thickness direction,
the protective film includes a first protective film,
the first protective film is provided with a second through-hole passing through the first protective film in the thickness direction,
the first through-hole and the second through-hole are in communication with each other and form a through-hole,
the first protective film includes a first grip portion at a peripheral edge portion of the first protective film, and
the first protective film includes a dividing portion that continues from the second through-hole to an end side of the first grip portion.

### Claim 2 (depends on 1)

The display panel provided with the protective film according to claim 1, wherein
the first grip portion protrudes from the peripheral edge portion of the first protective film in a direction away from the second through-hole, and
the dividing portion extends in a straight line from the second through-hole to the end side of the first grip portion.

### Claim 3

A display panel provided with a protective film, comprising:
a display panel; and
the protective film that is provided on a display surface of the display panel, wherein
the display panel is provided with a first through-hole passing through the display panel in a thickness direction,
the protective film includes a first protective film,
the first protective film is provided with a second through-hole passing through the first protective film in the thickness direction,
the first through-hole and the second through-hole are in communication with each other and form a through-hole,
the first protective film includes a first grip portion at a peripheral edge portion of the first protective film,
the first protective film includes a dividing portion that continues from the second through-hole to an end side of the first grip portion,
the protective film includes a second protective film on a surface of the first protective film opposite to the display panel, and
the second protective film covers at least the through-hole and the dividing portion.

### Claim 4 (depends on 3)

The display panel provided with the protective film according to claim 3, wherein the second protective film includes a second grip portion at a position at which the second protective film does not overlap the first protective film in plan view.

### Claim 5

A display panel provided with a protective film, comprising:
an organic electroluminescence display panel; and
the protective film that is provided on a display surface of the organic electroluminescence display panel, wherein
the organic electroluminescence display panel is provided with a first through-hole passing through the organic electroluminescence display panel in a thickness direction,
the protective film includes a first protective film,
the first protective film is provided with a second through-hole passing through the first protective film in the thickness direction,
the first through-hole and the second through-hole are in communication with each other and form a through-hole,
the first protective film includes a first grip portion at a peripheral edge portion of the first protective film,
the first protective film includes a dividing portion that continues from the second through-hole to an end side of the first grip portion,
the first grip portion protrudes from the peripheral edge portion of the first protective film in a direction away from the second through-hole, and
the dividing portion extends in a straight line from the second through-hole to the end side of the first grip portion.
