Abstract

There is provided a display device including: a display cell ( 20 ); a surrounding member ( 30 ) provided around the display cell ( 20 ); a cover film ( 10 ) provided on front side of the display cell ( 20 ) and the surrounding member ( 30 ); a relay member ( 40 ) provided on rear side of the display cell ( 20 ) and the surrounding member ( 30 ), and facing a margin between the display cell ( 20 ) and the surrounding member ( 30 ); and an adhesive layer ( 50 ) provided between the display cell ( 20 ) and the relay member ( 40 ), and between he surrounding member ( 30 ) and the relay member ( 40 ).

First claim

The invention claimed is:

1. A display device, comprising:
a display cell;
a surrounding member around the display cell;
a margin between the display cell and the surrounding member;
a cover film on a front side of the display cell, the margin, and the surrounding member;
a relay member on a first rear side of the display cell and on a second rear side of the surrounding member,
wherein the relay member faces the margin; and

an adhesive layer,
wherein a first portion of the adhesive layer is between the first rear side of the display cell and the relay member,
wherein a second portion of the adhesive layer is between the second rear side of the surrounding member and the relay member,
wherein the adhesive layer fills a recess between the display cell and the surrounding member, and
wherein three sides of the recess are surrounded by a first side surface of the display cell, a second side surface of the surrounding member, and the cover film.

2. The display device according to claim 1 ,
wherein the relay member comprises at least one of glass, carbon, or glass fiber.

3. The display device according to claim 1 ,
wherein the adhesive layer comprises an elastic material.

4. The display device according to claim 1 ,
wherein the relay member has a configuration to absorb a difference in expansion and contraction between the display cell and the surrounding member.

5. The display device according to claim 1 ,
wherein:
the cover film includes a front attachment part and an extended part outside the front attachment part,
the front attachment part is attached to the front side of the display cell and the surrounding member, and
the extended part is extended along the surrounding member towards a third rear side of the display cell.

6. The display device according to claim 5 , further comprising:
a rear casing on the third rear side of the display cell and a fourth rear side of the surrounding member; and
a movable coupling section configured to relatively movably couple the extended part of the cover film to the rear casing.

7. The display device according to claim 6 ,
wherein the movable coupling section includes:
a screw that couples the extended part of the cover film to the rear casing; and
a spring that energizes the screw in a first directions which is same as a second direction in which the extended part of the cover film is pulled toward the third rear side of the display cell.

8. The display device according to claim 1 ,
wherein the display cell is curved in a rearward-protruded arc shape.
