A holding mechanism of a display device includes a first arm, a second arm and a damper. The first arm and the second arm hold the display device in such a manner that the display device is capable of being displaced between a first disposition in which a lower edge portion of the display device is away from a placing face with a display screen facing to a front and a second disposition in which the lower edge portion is in contact with the placing face with the display screen facing more upward than in the first disposition. The damper applies, to the first arm, a force that buffers a force by which the display device is liable to displacement from the first disposition to the second disposition due to self-weight.
