Abstract: A three-dimensional display device prevents a barrier wire breakage failure and includes a parallax barrier panel resistant to static electricity. The 3D display device has a liquid crystal parallax barrier panel disposed over a display panel. The parallax barrier panel has a first substrate having an electrode formed flat thereon and a second substrate having a display area, the first substrate and the second substrate having liquid crystal sandwiched therebetween. The second substrate has barrier electrodes extending in a first direction and arrayed at a first pitch in a second direction, has a first bus electrode extending in the second direction outside the display area along a first side thereof, and has a second bus electrode extending in the second direction outside the display area along a second side thereof opposite to the first side. The barrier electrodes are connected to the first and the second bus electrodes.

Abstract: A display device includes a first pixel group and a second pixel group. A central value of positive-side and negative-side grayscale voltages of the first pixel group is set to be a fixed value. A common voltage is adjusted to its optimal value with respect to the first pixel group. A difference between the common voltage adjusted to the optimal value with respect to the first pixel group and an optimal common voltage of the second pixel group is corrected by shifting entire positive-side and negative-side grayscale voltages of the second pixel group in a vertical direction.
