Abstract

To provide a display device including a spacer, a flexible substrate having a wire extending from a terminal area to a display area, and a reinforcement film having a first reinforcement attached on the rear side of the display area, a second reinforcement attached on the display side of the terminal area, a bending reinforcement attached on the respective both edge portions in the width direction of the flexible substrate on the inside surface side of the bending area, and an opening surrounded by the first reinforcement, the second reinforcement, and the bending reinforcement, wherein the opening has a shape of which width becomes larger as it goes from respective end sides to center in the width direction of the reinforcement film.

Claims (20)

1. A display device comprising:

a spacer;

a flexible substrate on which a display area for image display, a frame area, a bending area, and a terminal area having a terminal are arranged in this order, and which includes a wire extending from the terminal area to the display area, the bending area being bent in conformity with a shape of the spacer to thereby place the terminal area on a rear side of the spacer; and

a reinforcement film including

a first reinforcement attached on a rear side of the display area,

a second reinforcement attached on a display side of the terminal area,

a bending reinforcement attached on respective both edge portions in a width direction of the flexible substrate on an inside surface side of the bending area, and

an opening surrounded by the first reinforcement, the second reinforcement, and the bending reinforcement,

wherein

the opening has a shape of which width becomes larger as the width goes from respective end sides to center in a width direction of the reinforcement film.

2. The display device according to claim 1 , wherein end faces of the first reinforcement and the second reinforcement that define the opening are flat faces.

3. The display device according to claim 2 , wherein the opening has a hexagonal shape.

4. The display device according to claim 1 , wherein an angle formed by each of end faces of the first reinforcement and the second reinforcement that define the opening and an end face of the bending reinforcement that defines the opening is an obtuse angle.

5. The display device according to claim 1 , wherein end faces of the first reinforcement and the second reinforcement that define the opening are curved faces.

6. The display device according to claim 1 , wherein end faces of the first reinforcement and the second reinforcement that define the opening are faces that smoothly extend from the respective end sides to center of the reinforcement film.

7. The display device according to claim 1 , wherein the opening has a symmetrical shape in the width direction of the reinforcement film.

8. The display device according to claim 1 , wherein end faces of the first reinforcement and the second reinforcement that define the opening include a plurality of convex and concave shapes.

9. The display device according to claim 1 , wherein

the spacer includes a guide portion for guiding the bending area in bending, a first base surface on which the first reinforcement which is recessed from the guide portion as a result of formation of a first step is attached, and a second base surface on which the second reinforcement which is recessed from the guide portion as a result of formation of a second step is attached, and

an end face of the first reinforcement that defines the opening partially has an abutting flat face for abutting against a rising face of the first step.
