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.
