Image display device

An image display device comprising:

• a display panel in which a plurality of sub-pixel pairs are horizontally disposed at predetermined pitches, the plurality of sub-pixel pairs each comprising two sub-pixels that display different images;
• and
• a parallax barrier shutter panel in which a plurality of sub-apertures are horizontally disposed, the plurality of sub-apertures being capable of being switched between a light-transmission state and a light-shielding state by driving a liquid crystal layer held between a first transparent substrate and a second transparent substrate with a plurality of vertically extending transparent electrodes,
• the display panel and the parallax barrier shutter panel being disposed in a stacked manner in the image display device,
• the first transparent substrate of the parallax barrier shutter panel comprising:
• in a display area, a plurality of lower-layer transparent electrodes disposed below an interlayer insulation film and a plurality of upper-layer transparent electrodes disposed on the interlayer insulation film as the plurality of transparent electrodes;
• in a first area adjacent to the display area, a wire for inputting a barrier control signal that is output from a drive circuit into the plurality of transparent electrodes, the barrier control signal being for controlling the parallax barrier shutter panel;
• and
• in a second area adjacent to the display area on an opposite side to the first area with respect to the display area, at least one common wire that sterically intersects with the plurality of transparent electrodes,
• the common wire being capable of being connected to any of the plurality of transparent electrodes by laser irradiation at an intersecting point between the common wire and the plurality of transparent electrodes.
