A conventional display device is constituted such that, when the display section is rotated to change the orientation thereof, the center of rotation and the center of the display section do not coincide, whereby the rotation operation lacks balance. Hence, the present invention provides a display device comprising a guide mechanism that comprises an annular track that rotates as the display section rotates and a guided member that is fixed to contact the annular track contained in the guide mechanism. By providing the annular track with recesses for fixing the position of the display section when the orientation of the display section is vertical or horizontal, the center of rotation and the center of the display section coincide, and also the screen height following the rotation can be optimized as a result of the rotation operation.
