Three dimensional display device comprising a second barrier electrode connected to one of a plurality of bus electrodes through a first barrier electrode and liquid crystal panel

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.
