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

A three-dimensional display device comprising a display panel and a parallax barrier panel, wherein:

• the parallax barrier panel has a first substrate, a second substrate, and liquid crystal sandwiched between the first substrate and the second substrate,
• the second substrate includes first barrier electrodes extending in a first direction and arranged at a first pitch in a second direction, second barrier electrodes extending in the first direction and arranged in the second direction, an insulating film interposed between the first barrier electrodes and the second barrier electrodes, and bus electrodes formed between the second substrate and the insulating film,
• the second barrier electrodes are arranged between the first barrier electrodes in a plan view,
• one of the first barrier electrodes is connected to one of the bus electrodes via a first through hole formed in the insulating film;
• one of the second barrier electrodes adjacent to the one of the first barrier electrodes is connected to the one of the first barrier electrodes via a second through hole formed in the insulating film,
• the second through hole does not overlap with the bus electrodes, and
• the one of the second barrier electrodes is connected to the one of the bus electrodes through the one of the first barrier electrodes.
