  However, in the invention described in Patent Document 1, it is necessary to use polarized glasses in order to view a stereoscopic image. Similarly, it is necessary to use polarized glasses to watch a similar movie in a movie theater.

  Here, in movie theaters or the like, generally, for example, simple polarized glasses such as a polarizing film corresponding to the left and right glasses are surrounded by a thick paper frame and distributed for viewing. However, viewers had to have movie pamphlets, catalogs for the next notice, and polarized glasses, which was difficult to manage.

  In addition, if a short video such as the next notice is shown in the movie hall or viewed on the TV in the hall, it can be viewed using polarized glasses, but if the brochure is distributed, the brochure It was necessary to have separately and was troublesome.

  The present invention has been made in view of such problems, and by combining a pamphlet or the like on which a next notice is printed in a movie theater with polarized glasses for viewing a stereoscopic image, the pamphlet is integrated. It is an object of the present invention to provide a film sheet for stereoscopic images that does not need to be separately provided and does not need to hold conventional polarized glasses.

The present invention is a film sheet in which a first polarizing portion and a second polarizing portion for stereoscopic glasses are formed on an end portion of a film base material in order to solve the above-described problems of the conventional technology, and the sheet Is a film sheet on which information related to objects to be viewed using stereoscopic glasses is printed.
The first polarizing portion and the second polarizing portion are film sheets formed by stretching a corresponding region of the film substrate.
The first polarizing part and the second polarizing part are film sheets formed by printing a first polarizing member and a second polarizing member in corresponding regions of the film base.
The first polarizing unit and the second polarizing unit provide a film sheet formed by applying a first polarizing member and a second polarizing member to corresponding regions of the film base.

  According to the film sheet of the present invention, it is not necessary to have the pamphlet separately by integrating the pamphlet on which the next notice is printed in the movie theater and the polarizing glasses for viewing the stereoscopic image. There is no need to hold conventional polarized glasses.
