## Abstract

Provided is a display unit that includes: a display panel having a pair of substrates that are bonded to each other in a seal region along an outer edge of the display panel; a transparent plate facing the display panel; an optical film provided on a surface of the display panel which faces the transparent plate, and having an outer edge positioned over the seal region; and a resin layer sandwiched between the optical film and the transparent plate.

## Claims

### Claim 1

A display unit comprising:
a display panel having associated therewith a first axis direction and a second axis direction orthogonal to the first axis direction, said display panel having a pair of substrates, the substrates being bonded to each other in a seal region along an outer portion of the display panel;
a transparent plate facing the display panel;
an optical film provided on a surface of the display panel which faces the transparent plate, and having an outer edge positioned over the seal region such that the outer edge of the optical film is positioned along one of the first axis direction or the second axis direction between an inner edge of the seal region and before an outer edge of the display panel; and
a resin layer sandwiched between the optical film and the transparent plate,
an outer edge of the resin layer is positioned along the one of the first axis direction or the second axis direction between the outer edge of the optical film and the outer edge of the display panel such that the resin layer (i) covers an entirety of a surface of the optical film which faces the transparent plate, (ii) covers a first part of the surface of the display panel, and (iii) does not cover a second part of the surface of the display panel, said first part and said second part of the surface of the display panel are not covered by the optical film.

### Claim 2 (depends on 1)

The display unit according to claim 1, wherein the resin layer covers the outer edge of the optical film.

### Claim 3 (depends on 1)

The display unit according to claim 1, wherein the resin layer contains a particle-shaped spacer having a diameter corresponding to a thickness of the resin layer.

### Claim 4

A display unit comprising:
a display panel having associated therewith a first axis direction and a second axis direction orthogonal to the first axis direction;
a transparent plate facing the display panel;
an optical film provided on a surface of the display panel which faces the transparent plate; and
a resin layer sandwiched between the optical film and the transparent plate, and having an outer edge positioned on an inner side of an outer edge of the optical film such that the outer edge of the optical film extends in one of the first axis direction or the second axis direction beyond the outer edge of the resin layer such that the resin layer covers a first part of a surface of the optical film which faces the transparent plate and does not cover a second part of the surface of the optical film which faces the transparent plate.

### Claim 5 (depends on 4)

The display unit according to claim 4, wherein
the display panel has a pair of substrates, the substrates being bonded to each other in a seal region along an outer portion of the display panel, and
the outer edge of the optical film is positioned over the seal region such that the outer edge of the optical film is positioned along the one of the first axis direction or the second axis direction between an inner edge of the seal region and an outer edge of the display panel.

### Claim 6 (depends on 4)

The display unit according to claim 4, wherein the resin layer contains a particle-shaped spacer having a diameter corresponding to a thickness of the resin layer.

### Claim 7 (depends on 1)

The display unit according to claim 1, wherein the display panel has a plurality of pixels, 3840 or more of the pixels being arranged in a first direction, and 2160 or more of the pixels being arranged in a second direction.

### Claim 8 (depends on 7)

The display unit according to claim 7, wherein each of the pixels includes a first sub-pixel, a second sub-pixel, and a third sub-pixel, the first sub-pixel emitting red light, the second sub-pixel emitting green light, the third sub-pixel emitting blue light.
