Description

The present invention relates to a screen manufacturing method and a screen.

2. Description of the Related Art Conventionally, there has been known a chair that allows a user to use a personal computer or the like in a relatively relaxed posture (see Patent Document 1, for example).

By the way, among chairs of this type, those that partially enclose the user's surroundings so that the user can obtain a semi-private room feeling in which the user can concentrate on his/her work or the like are beginning to appear.

For such a chair, it is also being considered to provide a wall surrounding the user and a screen around the wall that can suppress visibility from the outside in order to give a feeling of a substantial private room.

However, most of the conventional screens are in the form of flat standing walls, and cannot form a three-dimensional shape that protrudes outward. Therefore, when the user is surrounded by the conventional one, the flat form is visually recognized by the user, and the internal space tends to feel cramped.

In other words, most conventional screens can take a flat plate-like or wall-like form, making it difficult to form a three-dimensional shape that can improve design and functionality.

It should be noted that the above situation is not limited to the screen used to enclose the surroundings of the user, and the same applies to general screens that can suppress visual recognition from the outside.
