Abstract

An image display apparatus includes a parallax-barrier shutter panel including a plurality of sub-pixels arranged widthwise, the sub-pixels each being changeable between a light transmittance state and a light block state by driving a liquid crystal layer held between a first transparent substrate and a second transparent substrate with a first transparent electrode extending lengthwise. The first transparent substrate includes in a display area, a lower-layer first transparent electrode disposed under an interlayer insulating film and an upper-layer first transparent electrode disposed on the interlayer insulating film, the lower-layer first transparent electrode and the upper-layer first transparent electrode being the first transparent electrode. The first transparent substrate includes in an area adjacent to the display area, a lower-layer metal wire disposed under the interlayer insulating film and an upper-layer metal wire disposed on the interlayer insulating film. A lower-layer transparent electrode is connected to the lower-layer metal wire.

Claims (15)

1. An image display apparatus comprising a stacked arrangement of a display panel and a parallax-barrier shutter panel,

the display panel comprising a plurality of sub-pixel pairs arranged widthwise at a predetermined pitch, the plurality of sub-pixel pairs each being formed of two sub-pixels displaying different images from each other,

the parallax-barrier shutter panel comprising a plurality of sub-openings arranged widthwise, the plurality of sub-openings each being changeable between a light transmittance state and a light block state by driving a liquid crystal layer held between a first transparent substrate and a second transparent substrate with a transparent electrode extending lengthwise,

the first transparent substrate of the parallax-barrier shutter panel comprising

in a display area, a lower-layer transparent electrode disposed under an interlayer insulating film and an upper-layer transparent electrode disposed on the interlayer insulating film, the lower-layer transparent electrode and the upper-layer transparent electrode being the transparent electrode, and

in an area adjacent to the display area, a lower-layer metal wire disposed under the interlayer insulating film and an upper-layer metal wire disposed on the interlayer insulating film,

the lower-layer transparent electrode being connected to the lower-layer metal wire.

2. The image display apparatus according to claim 1 , wherein the upper-layer transparent electrode is connected to the upper-layer metal wire.

3. The image display apparatus according to claim 1 , wherein the upper-layer transparent electrode is connected to the upper-layer metal wire through the lower-layer metal wire.

4. The image display apparatus according to claim 1 , wherein the lower-layer metal wire is formed in a layer directly on or directly under the lower-layer transparent electrode.

5. The image display apparatus according to claim 1 , wherein the upper-layer metal wire is formed in a layer directly on or directly under the upper-layer transparent electrode.

6. The image display apparatus according to claim 1 , wherein an electrical connection between the lower-layer metal wire and the upper-layer metal wire is established through a connection wire formed of a transparent conductive film in the same layer as the upper-layer transparent electrode via a contact hole formed in the interlayer insulating film.

7. The image display apparatus according to claim 1 , wherein the upper-layer transparent electrodes that are in electrical common or the lower-layer transparent electrodes that are in electrical common are electrically connected to the upper-layer metal wire in common.

8. The image display apparatus according to claim 1 , wherein the upper-layer metal wire comprises an upper surface covered in whole with a transparent conductive film in the same layer as the upper-layer transparent electrode.

9. The image display apparatus according to claim 1 , further comprising a protective insulating film disposed on the upper-layer transparent electrode and the upper-layer metal wire.
