Abstract

An organic EL display device includes: a first support member having flexibility; an organic EL layer layered in a matrix form on the first support member; and a second support member disposed opposite the first support member with the organic EL layer interposed between the first support member and the second support member. Grooves on the first support member and grooves on the second support member overlap with one another. As a result, flexibility of the organic EL display device can be enhanced.

Claims (18)

1. An organic EL display device, comprising:

a first support member having flexibility;

an organic EL layer formed in a matrix form on the first support member; and

a second support member having flexibility and disposed opposite the first support member with the organic EL layer interposed between the first support member and the second support member,

wherein the first support member and the second support member each include an outside surface on which a plurality of bulging portions is formed,

grooves between the bulging portions of the first support member and grooves between the bulging portions of the second support member overlap with one another,

the grooves formed on one of the first support member and the second support member that is located on an image display surface side overlap with pixels on which the organic EL layer is disposed, and shapes of the grooves overlapping with the pixels are the same, and

a pitch of the pixels is an integer multiple of a distance between the grooves formed on one of the first display member and the second display member that is located on the image display surface side.

2. The organic EL display device according to claim 1 ,

wherein a plurality of the bulging portions formed on one of the first support member and the second support member that is located on the image display surface side overlap with the pixels.

3. The organic EL display device according to claim 1 ,

wherein one of a distance between the grooves adjacent to each other on the first support member and a distance between the grooves adjacent to each other on the second support member is an integer multiple of the other.

4. The organic EL display device according to claim 3 ,

wherein a plurality of the bulging portions formed on one of the first support member and the second support member that is located on the image display surface side overlap with the pixels.

5. The organic EL display device according to claim 3 ,

wherein the distance between the grooves adjacent to each other on the first support member and the distance between the grooves adjacent to each other on the second support member are equal.

6. The organic EL display device according to claim 5 ,

wherein a plurality of the bulging portions formed on one of the first support member and the second support member that is located on the image display surface side overlap with the pixels.
