Abstract: A parallax barrier panel including a first substrate having a flat electrode, and a second substrate, the liquid crystal sandwiched therebetween. The second substrate has first barrier electrodes extending in a first direction and arrayed at a first pitch in a second direction, and has second barrier electrodes, the first and the second harrier electrodes having an interlayer insulating film interposed therebetween. Gaps between the first barrier electrodes are blocked by the second barrier electrodes when viewed in a plan view. Each of the first barrier electrodes is paired with one of the second barrier electrodes. Bus electrodes extend outside the display area along a side thereof. The first barrier electrodes are connected to the bus electrodes via first through holes formed in the interlayer insulating film. The second barrier electrodes are connected to the first barrier electrodes via second through holes formed in the interlay insulating film.

Abstract: A parallax barrier panel includes plural sub-areas which are arranged in an X direction, plural light-shielding area each of which includes the plural sub-areas in a light-shielding state, and plural light-transmitting areas each of which includes the plural sub-areas in a light-transmitting state and which are arranged alternately with the plural light-shielding areas in the X direction. The sub-areas extend in a Y direction and can be switched between the light-transmitting state and the light-shielding state. Each of the sub-areas is provided with an electrode for controlling a liquid crystal layer. A first electric line is connected to an upper end part of the electrode, and a second electric line is connected to a lower end part of the electrode.

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: Second barrier electrodes are arranged under first barrier electrodes so as to fill gaps between the first barrier electrodes, while an insulating layer is located between the first barrier electrodes and the second barrier electrodes. The number of first barrier electrodes and the number of second barrier electrodes in each barrier pitch are 6 or more. The positions of the barriers formed by the first barrier electrodes and the second barrier electrodes are controlled by the reception of a signal representing detected positions of the eyes of a viewer. If pitches of the first barrier electrodes are defined as BE, and the widths of regions in which the first barrier electrodes are overlapped with the second barrier electrodes are defined as BA, a ratio BA/BE of the widths BA to the pitches BE are 0.3 or smaller. This configuration can suppress the occurrence of moire.
