  However, as described above, in the conventional technique, the liquid crystal shutter switching signal is transmitted in only one direction in which the image display device is the transmission side and the stereoscopic image glasses are the reception side. For this reason, information regarding stereoscopic image glasses cannot be transmitted to the image display device. Therefore, for example, when a defect or the like occurs in the stereoscopic image glasses, the user cannot immediately know what is happening in the stereoscopic image glasses, which is inconvenient. In addition, since the stereoscopic image glasses receive only signals for switching the liquid crystal shutter, there is a problem in operation.

  Accordingly, the present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide stereoscopic image glasses and images that can improve the convenience for the user and provide a comfortable viewing environment for the user.
