Abstract:
1. An image display device comprising: a signal control portion that receives input of an image signal, and outputs a signal that causes an image for a right eye and an image for a left eye to be displayed alternately; a display panel to which the signal converted by the signal control portion is input, and which alternately displays the image for the right eye and the image for the left eye; and a polarity reversing portion that performs polarity reversal of a drive voltage of the display panel due to the signal, wherein each said image for the right eye and each said image for the left eye corresponds to a respective frame, wherein the signal outputted from the signal control portion causes each frame of the image for the left (L) eye and each frame of the image for the right (R) eye to be written twice in a consecutive manner so as to provide an image sequence of L (a first time), L (a second time), R (a first time), and R (a second time), wherein in the image sequence of the first time L, the second time L, the first time R, and the second time R, only the images of the second time L and the second time R, are caused to be displayed for view by a user, wherein a predetermined blank period is inserted between (i) the L of the first time and the L of the second time, and (ii) the R of the first time and the R of the second time, and wherein the polarity reversing portion performs polarity reversal of the drive voltage once in every four frames or once in every 4N frames, in which N is a positive integer.
