Abstract:
1. A stereoscopic image display device comprising: a display device that time-division displays a right eye image and a left eye image; polarization glasses in which a polarization characteristic of a right lens and a polarization characteristic of a left lens are different from each other; a polarization switching element between the display device and the polarization glasses, the polarization switching element including a plurality of scan electrode lines, the polarization switching element switching a polarization characteristic of light travelling to the polarization glasses according to a voltage supplied to the scan electrode lines; a driver that supplies a first voltage synchronized with the right eye image displayed on the display device to the scan electrode lines and supplies a second voltage synchronized with the left eye image displayed on the display device to the scan electrode lines; and a controller that supplies right eye video data of the right eye image and left eye video data of the left eye image to the display device and controls the driver so that a voltage of the scan electrode lines of the polarization switching element varies from the first voltage to the second voltage along a line of the display device in which the image displayed changes from the right eye image to the left eye image and the voltage of the scan electrode lines of the polarization switching element varies from the second voltage to the first voltage along a line of the display device in which the image displayed changes from the left eye image to the right eye image.
