This is to prevent the image R from entering the left eye of the observer H.

  FIG. 2 is a plan view showing a pixel arrangement in the liquid crystal panel 3. As shown in FIG. 2, a plurality of substantially square pixels 100 are arranged. Each pixel 100 includes four sub-pixels 100R, 100G, 100B, and 100W to which color filters of red (R), green (G), blue (B), and white (W) are assigned, respectively. . In the present embodiment, these four sub-pixels 100R, 100G, 100B, and 100W are configured with substantially the same size in a substantially square shape. Therefore, the pitch between adjacent sub-pixels 100R, 100G, 100B, and 100W is set equal.

FIG. 3 shows a pixel arrangement state in a state where the liquid crystal panel 3 (stereoscopic image display device 1) is placed vertically.

  When viewed in the vertical direction (vertical direction in FIG. 3), the arrangement order of the right-eye image R and the left-eye image L is reversed in adjacent pixel rows. In FIG. 3, the first-row pixels 100 are arranged in the order of the right-eye image R and the left-eye image L, and the second-row pixels 100 are arranged in the left-eye image L and the right-eye image. They are arranged in the order of the image R.

  The light shielding barrier 2 generates a barrier opening S at a position where the right-eye image R and the left-eye image L are separated.

Polarizing plates 14 and 16 are provided on the outer surfaces of the glass substrates 11 and 12, respectively. Of these two polarizing plates 14 and 16, the polarizing plate 14 on the liquid crystal panel 3 side that displays an image can be shared with a polarizing plate (not shown) of the liquid crystal panel 3. The polarizing plate 14 and the polarizing plate 16 are attached so that the polarization axes are orthogonal to each other. A first electrode 10 is provided on the inner surface side (liquid crystal layer 13 side) of one glass substrate 11. A second electrode 15 is formed on the inner surface side (liquid crystal layer 13 side) of the other glass substrate 12. The first electrode 10 and the second electrode 15 are made of, for example, ITO.

  FIG. 5 is a plan view showing the shape of the first electrode 10 formed on the glass substrate 11. As shown in FIG. 5, the first electrode 10 includes a vertical drive electrode portion 10a and a horizontal drive electrode portion 10b. The vertical drive electrode portion 10a and the horizontal drive electrode portion 10b are insulated from each other.

  The vertical drive electrode portion 10a includes a plurality of substantially rectangular rectangular electrodes 30, and these rectangular electrodes 30 are arranged in a staggered manner and connected to each other. Each rectangular electrode 30 functions as a barrier opening S (see FIG. 3) of the light shielding barrier 2. Similarly to the vertical drive electrode portion 10a, the horizontal drive electrode portion 10b includes a plurality of rectangular electrodes 30, and the rectangular electrodes 30 are arranged in a staggered manner and electrically connected to each other. It has become. The vertical drive electrode portions 10a and the horizontal drive electrode portions 10b are alternately formed, whereby the first electrode 10 is disposed over substantially the entire surface of the glass substrate 11. Yes.

  The vertical drive electrode unit 10a and the horizontal drive electrode unit 10b are electrically connected to the vertical drive unit 21 and the horizontal drive unit 22, respectively, and are independently driven. It is possible. These vertical drive unit 21 and horizontal drive unit 22 are constituted by a circuit unit including, for example, a switching circuit.

  Based on such a configuration, the vertical drive electrode unit 10a is driven when the stereoscopic image display device 1 is placed vertically. Unlike the vertically placed drive electrode portion 10a, the horizontally placed drive electrode portion 10b is driven only when the stereoscopic image display device 1 is placed horizontally. Note that the vertical drive electrode unit 10a is set to a size and a position capable of satisfactorily separating the right-eye image R and the left-eye image L when vertically placed.

  FIG. 6 is a plan view showing the shape of the second electrode 15 formed on the glass substrate 12. As shown in FIG. 6, the second electrode 15 includes a lateral drive electrode portion 15a and a vertical drive electrode portion 15b. The horizontal drive electrode portion 15a and the vertical drive electrode portion 15b are electrically insulated from each other.

  The lateral drive electrode portion 15a includes a plurality of rectangular electrodes 35. The rectangular electrodes 30 are arranged in a staggered manner and connected to each other. Each rectangular electrode 35 functions as a barrier opening of the light shielding barrier 2. Similarly to the horizontal drive electrode portion 15a, the vertical drive electrode portion 15b includes a plurality of rectangular electrodes 35, and the rectangular electrodes 30 are arranged in a staggered manner and electrically connected to each other. It has become. The horizontal drive electrode portions 15a and the vertical drive electrode portions 15b are alternately formed, whereby the second electrode 15 is disposed on substantially the entire surface of the glass substrate 12.

  In addition, a horizontal drive unit 41 and a vertical drive unit 42 are electrically connected to the horizontal drive electrode unit 15a and the vertical drive electrode unit 15b, respectively, and are independently driven. It is possible. The horizontal drive unit 41 and the vertical drive unit 42 are configured by a circuit unit including, for example, a switching circuit.

Based on such a configuration, the lateral drive electrode unit 15a is driven when the stereoscopic image display apparatus 1 is laterally placed. Unlike the horizontal drive electrode unit 15a, the vertical drive electrode unit 15b is driven only when the stereoscopic image display device 1 is installed vertically. Note that the lateral drive electrode unit 15a is set to a size and a position where the right-eye image R and the left-eye image L can be satisfactorily separated when laterally placed.
As described above, the light-shielding barrier 2 can be configured to have different light-shielding barrier shapes according to the installation state of the stereoscopic image display device 1 (vertical or horizontal).

  The light-shielding barrier 2 operates only the vertical drive unit 21 on the glass substrate 11 side when the stereoscopic image display device 1 is placed vertically, and the horizontal drive unit 41 and vertical drive unit 42 on the glass substrate 12 side. Work. Thereby, on the glass substrate 12 side, the entire surface of the second electrode 15 can be set to a common potential.

  Here, the vertical drive electrode unit 10a and the horizontal drive electrode unit 10b on the glass substrate 11 side, and the horizontal drive electrode unit 15a and the vertical drive electrode unit 15b on the glass substrate 12 side are shown in FIG. The planar positional relationship is as shown. Since this figure is a schematic diagram, there is a gap between the vertical drive electrode portion 15a and the horizontal drive electrode portion 15b constituting the second electrode 15, but the actual gap is very small. For this reason, a voltage can be favorably applied between the second electrode 15 and the drive electrode portion 10a when placed vertically. Thereby, the polarization axis of the light polarized by the polarizing plate 14 is rotated by 90 degrees in accordance with the rotation of the liquid crystal in the liquid crystal layer 13 positioned between the longitudinal drive electrode portion 10a and the second electrode 15, The light passes through the polarizing plate 16 and comes out. At this time, since no voltage is applied between the lateral drive electrode portion 10b and the second electrode 15, the polarization axis of the light selected by the polarizing plate 14 does not rotate in the liquid crystal layer 13, It does not pass through the polarizing plate 16.

  As a result, the barrier openings S formed by the light shielding barrier 2 have a staggered shape corresponding to the pattern (first barrier pattern) of the drive electrode portion 10a when vertically disposed as shown in FIG. Therefore, the right-eye image R and the left-eye image L can be satisfactorily separated, and the observer H can surely visually recognize the right-eye image R and the left-eye image L.

  The stereoscopic image display device 1 includes a sub-pixel group (two sub-pixels) that displays the right-eye image R and a sub-pixel group (two sub-pixels) that displays the left-eye image L even when the image is horizontally placed. ) Is a staggered arrangement.

  The light shielding barrier 2 operates only the horizontal drive unit 41 on the glass substrate 12 side when the stereoscopic image display device 1 is placed horizontally, and the vertical drive unit 21 and horizontal drive unit 22 on the glass substrate 11 side. Work. At this time, the entire surface of the first electrode 10 has a common potential. Therefore, a voltage can be applied between the lateral drive electrode portion 15 a and the first electrode 10 on the glass substrate 12 side, as in the vertical placement. Thereby, the polarization axis of the light polarized by the polarizing plate 14 is rotated by 90 degrees in accordance with the rotation of the liquid crystal in the liquid crystal layer 13 positioned between the lateral drive electrode portion 15a and the first electrode 10, The light passes through the polarizing plate 16 and comes out. At this time, since no voltage is applied between the longitudinal drive electrode portion 15b and the first electrode 10, the polarization axis of the light selected by the polarizing plate 14 does not rotate in the liquid crystal layer 13, It does not pass through the polarizing plate 16.

  As a result, the barrier openings S formed by the light-shielding barrier 2 have a rectangular shape corresponding to the pattern (second barrier pattern) of the lateral drive electrode portion 15a as shown in FIG. 8, and these are arranged in a staggered manner. It will be a thing. Therefore, the right-eye image R and the left-eye image L can be satisfactorily separated, and the observer H can surely visually recognize the right-eye image R and the left-eye image L.

  In this way, the light blocking barrier 2 causes the binocular parallax effect by causing only the right-eye image R to enter the right eye of the observer H and causing only the left-eye image L to enter the left eye of the observer H. The stereoscopic image can be visually recognized by the observer H.

  In the stereoscopic image display device 1 according to the present embodiment, since the shape of each of the sub-pixels 100R, 100G, 100B, and 100W is substantially square as described above, the pitch between the sub-pixels changes between vertically and horizontally. There is nothing. Therefore, the viewing distance of the liquid crystal panel 3 of the observer H does not change. Moreover, since the barrier shape corresponding to the vertical placement and the horizontal placement is set, a good stereoscopic image can be viewed without changing the viewer H stereoscopic image viewing position in both the vertical placement and the horizontal placement. Can be made. In addition, since the pixel 100 includes four colors of R (red), G (green), B (blue), and W (white), a high-quality stereoscopic image can be displayed.

As shown in FIG. 11, the first electrode 10 includes a vertical drive electrode portion 110a and a horizontal drive electrode portion 110b. The vertical drive electrode unit 110a and the horizontal drive electrode unit 110b are electrically insulated from each other.

  The longitudinal drive electrode portion 110a includes slit-like slit electrodes 130, and these slit electrodes 130 are arranged in a stripe shape and are connected to each other. Each slit electrode 130 functions as a barrier opening S of the light shielding barrier 2. Similarly to the vertical drive electrode portion 110a, the horizontal drive electrode portion 110b includes a plurality of slit electrodes 130. The slit electrodes 130 are arranged in stripes and are electrically connected to each other. It has become. The vertical drive electrode portions 110a and the horizontal drive electrode portions 110b are alternately formed, whereby the first electrode 10 is disposed over substantially the entire surface of the glass substrate 11. Yes. Note that the vertical drive electrode unit 110a is set to a size and a position at which the right-eye image R and the left-eye image L can be satisfactorily separated when vertically placed.

  The vertical drive electrode unit 110a and the horizontal drive electrode unit 110b are electrically connected to the vertical drive unit 21 and the horizontal drive unit 22, respectively, and are independently driven. It is possible.

  FIG. 12 is a plan view showing the shape of the second electrode 15 formed on the glass substrate 12. As shown in FIG. 12, the second electrode 15 includes a lateral drive electrode portion 115a and a vertical drive electrode portion 115b. The horizontal drive electrode portion 115a and the vertical drive electrode portion 115b are electrically insulated from each other.

  The lateral drive electrode portion 115a includes slit-shaped slit electrodes 130, and the slit electrodes 130 are arranged in stripes and are connected to each other. Each slit electrode 130 functions as a barrier opening of the light shielding barrier 2. Similarly to the horizontal drive electrode portion 115a, the vertical drive electrode portion 115b includes a plurality of slit electrodes 130, and the slit electrodes 130 are arranged in stripes and are electrically connected to each other. It has become. The horizontal drive electrode portions 115a and the vertical drive electrode portions 115b are alternately formed, whereby the second electrode 15 is disposed over substantially the entire surface of the glass substrate 11. Yes. Note that the lateral drive electrode unit 115a is set to a size and a position capable of satisfactorily separating the right-eye image R and the left-eye image L when laterally placed. Specifically, the vertical drive electrode unit 110a and the horizontal drive electrode unit 110b on the glass substrate 11 side, and the horizontal drive electrode unit 115a and the vertical drive electrode unit 115b on the glass substrate 12 side are shown in FIG. As shown in FIG.

  In the present embodiment, since the first electrode 10 and the second electrode 15 forming the barrier pattern of the light shielding barrier 2 have a stripe shape, the manufacturing process of the light shielding barrier 2 can be simplified as compared with the first embodiment. Can do.

  Further, the horizontal drive electrode unit 115a and the vertical drive electrode unit 115b are electrically connected to the horizontal drive unit 41 and the vertical drive unit 42, respectively, and are independently driven. It is possible.

  The light shielding barrier 2 operates only the vertical drive unit 21 and also operates the horizontal drive unit 41 and the vertical drive unit 42 on the glass substrate 12 side when the stereoscopic image display device 1 is placed vertically. Thereby, on the glass substrate 12 side, the entire surface of the second electrode 15 can be set to a common potential.

  Here, the vertical drive electrode unit 110a and the horizontal drive electrode unit 110b on the glass substrate 11 side, and the horizontal drive electrode unit 115a and the vertical drive electrode unit 115b on the glass substrate 12 side are shown in FIG. The planar positional relationship is as shown. Since this figure is a schematic diagram, there is a gap between the vertical drive electrode portion 115a and the horizontal drive electrode portion 115b constituting the second electrode 15, but the actual gap is very small. For this reason, the voltage can be favorably applied between the second electrode 15 and the drive electrode portion 110a when vertically arranged. Thereby, the polarization axis of the light polarized by the polarizing plate 14 is rotated by 90 degrees in accordance with the rotation of the liquid crystal in the liquid crystal layer 13 positioned between the longitudinal drive electrode portion 110a and the second electrode 15, The light passes through the polarizing plate 16 and comes out. At this time, since no voltage is applied between the lateral drive electrode portion 110b and the second electrode 15, the polarization axis of the light selected by the polarizing plate 14 does not rotate in the liquid crystal layer 13, It does not pass through the polarizing plate 16.

Therefore, the barrier opening S formed by the light shielding barrier 2 has a slit shape corresponding to the pattern of the drive electrode portion 110a when vertically disposed as shown in FIG. Therefore, the right-eye image R and the left-eye image L can be satisfactorily separated, and the observer H can surely visually recognize the right-eye image R and the left-eye image L.
Even when the stereoscopic image display device 1 is placed horizontally, the sub-pixels that display the right-eye image R and the sub-pixel groups that display the left-eye image L are arranged in stripes.

  The light blocking barrier 2 operates only the horizontal drive unit 41 and the vertical drive unit 21 and the horizontal drive unit 22 when the stereoscopic image display device 1 is placed horizontally. At this time, since the entire surface of the first electrode 10 is at a common potential, a voltage can be applied between the lateral drive electrode portion 115 a and the first electrode 10. Thereby, the polarization axis of the light polarized by the polarizing plate 14 is rotated by 90 degrees according to the rotation of the liquid crystal in the liquid crystal layer 13 positioned between the lateral drive electrode portion 115a and the first electrode 10, The light passes through the polarizing plate 16 and comes out. At this time, since no voltage is applied between the longitudinal drive electrode portion 115b and the first electrode 10, the polarization axis of the light selected by the polarizing plate 14 does not rotate in the liquid crystal layer 13. It does not pass through the polarizing plate 16.

  As a result, the barrier opening S formed by the light shielding barrier 2 has a slit shape corresponding to the pattern of the lateral drive electrode portion 115a as shown in FIG. 14, and these are arranged in stripes. Therefore, the right-eye image R and the left-eye image L can be satisfactorily separated, and the observer H can surely visually recognize the right-eye image R and the left-eye image L.

  In this way, the light blocking barrier 2 causes the binocular parallax effect by causing only the right-eye image R to enter the right eye of the observer H and causing only the left-eye image L to enter the left eye of the observer H. The stereoscopic image can be visually recognized by the observer H.

  Also in this embodiment, since the shape of each of the sub-pixels 100R, 100G, 100B, and 100W is substantially square, the stereoscopic image viewing position of the observer H is not changed in both vertical and horizontal positions. 3D images can be visually recognized.
