The second light shielding film 20 is formed on the second substrate 18. The second light shielding film 20 has a plurality of second fixed openings 22. The second fixed opening 22 is disposed such that the center and any of the first fixed openings 16 are offset. Further, the first fixed opening 16 and the second fixed opening 22 may be shifted so as not to overlap at all as shown in FIG. 1 or 2, or the ends may overlap each other.

圖2係用以說明第1固定開口16及第2固定開口22之形狀及配置之圖。複數個第1固定開口16各自以於任意方向(例如相同方向)變長之方式形成。包含至少1個第1固定開口16之右側開口RO與包含其他至少1個第1固定開口16之左側開口LO係成對構成1個像素14。構成右側開口RO之至少1個第1固定開口16、與構成左側開口LO之至少1個第1固定開口16係空開間隔而配置。第1固定開口16係於與其間隔正交之 方向上變長。 FIG. 2 is a view for explaining the shape and arrangement of the first fixed opening 16 and the second fixed opening 22.

The first fixed opening 16 is orthogonal to the interval The direction becomes longer.

複數個第2固定開口22各自以於任意方向(例如同方向)變長之方式形成。複數個第2固定開口22各自以於與複數個第1固定開口16變長之方向相同之方向上變長之方式形成。相鄰之第2固定開口22彼此之間隔大於相鄰之右側開口RO及左側開口LO彼此之間隔。 Each of the plurality of second fixed openings 22 is formed to be elongated in an arbitrary direction (for example, the same direction). Each of the plurality of second fixed openings 22 is formed to be long in the same direction as the direction in which the plurality of first fixed openings 16 are elongated. The distance between the adjacent second fixed openings 22 is greater than the interval between the adjacent right side opening RO and the left side opening LO.

如圖1所示，立體顯示裝置具有背光源24。背光源24重疊於第2基板18。藉此，背光源24係自第2基板18朝第1基板10之方向出射光。通過各個第2固定開口22之光係沿右側開口RO及左側開口LO之至少一者傾斜地行進。通過右側開口RO之光與通過左側開口LO之光於第1基板10之外側沿彼此分離之方向行進。通過右側開口RO之光與通過左側開口LO之光各自係自各個第2固定開口22朝相互接近之方向行進且於交叉後朝相互分離之方向行進之光。 As shown in FIG. 1, the stereoscopic display device has a backlight 24. The backlight 24 is superposed on the second substrate 18. Thereby, the backlight 24 emits light from the second substrate 18 in the direction of the first substrate 10. The light passing through each of the second fixed openings 22 travels obliquely along at least one of the right opening RO and the left opening LO. The light passing through the right opening RO and the light passing through the left opening LO travel in a direction separating from each other on the outer side of the first substrate 10. The light passing through the right opening RO and the light passing through the left opening LO are light that travels from the respective second fixed openings 22 toward each other and travels in a direction separating from each other after the intersection.

於第1基板10與第2基板18之間設置有複數個快門26。於第1基板10設置有複數個(多個)快門26。快門26係設置於未圖示之薄膜電晶體或配線等上。 A plurality of shutters 26 are provided between the first substrate 10 and the second substrate 18. A plurality of shutters (s) 26 are provided on the first substrate 10. The shutter 26 is provided on a thin film transistor, wiring, or the like (not shown).

圖3係快門及其驅動部之立體圖。快門26包含無機材料。快門26被支撐於第1彈簧28且自第1基板10上浮。藉由複數個第1彈簧28支撐快門26。第1彈簧28以第1錨定部30固定於第1基板10。第1彈簧28包含可彈性變形之材料。第1彈簧28呈厚度較薄之板狀，且將厚度方向朝向橫向(平行於第1基板10之板面之方向)、將寬度方向朝向上下方向(垂直於第1基板10之板面之方向)而配置。藉此，第1彈簧28可於其厚度方向即橫向上變形。快門26以可於圖3中箭頭所示之方向移動之方式被支撐於第1彈簧28。 Figure 3 is a perspective view of the shutter and its driving portion. The shutter 26 contains an inorganic material. The shutter 26 is supported by the first spring 28 and floats from the first substrate 10 . The shutter 26 is supported by a plurality of first springs 28. The first spring 28 is fixed to the first substrate 10 by the first anchor portion 30. The first spring 28 contains an elastically deformable material. The first spring 28 has a plate shape having a small thickness, and faces the thickness direction in the lateral direction (parallel to the plate surface of the first substrate 10) and the width direction in the vertical direction (perpendicular to the plate surface of the first substrate 10). ) and configured. Thereby, the first spring 28 can be deformed in the thickness direction thereof, that is, in the lateral direction. The shutter 26 is supported by the first spring 28 so as to be movable in the direction indicated by the arrow in FIG.

於第1基板10設置有被支撐於第2錨定部32之第2彈簧34。第2彈簧34亦包含可彈性變形之材料。第2彈簧34呈厚度較薄之板狀，且將厚度方向朝向橫向(平行於第1基板10之板面之方向)、將寬度方向朝 向上下方向(垂直於第1基板10之板面之方向)而配置。藉此，第2彈簧34可於其厚度方向即橫向上變形。又，第2彈簧34呈環狀，自第2錨定部32延伸之帶狀部被彎曲折回，並返回至同一第2錨定部32。 The second substrate 34 supported by the second anchor portion 32 is provided on the first substrate 10 . The second spring 34 also includes an elastically deformable material. The second spring 34 has a plate shape having a small thickness, and the thickness direction is oriented in the lateral direction (parallel to the direction of the plate surface of the first substrate 10), and the width direction is It is arranged in the up-down direction (the direction perpendicular to the board surface of the 1st board|substrate 10). Thereby, the second spring 34 can be deformed in the thickness direction thereof, that is, in the lateral direction. Further, the second spring 34 has an annular shape, and the strip portion extending from the second anchor portion 32 is bent back and returned to the same second anchor portion 32.

第2彈簧34在較第1彈簧28距離快門26更遠之側與第1彈簧28對向。對第2錨定部32施加電壓，藉由因與第1彈簧28之電位差所產生之靜電引力而使第1彈簧28被第2彈簧34牽引。若第1彈簧28被牽引，則快門26亦受牽引。即，第1彈簧28及第2彈簧34係用以構成用以機械驅動快門26之驅動部36者。驅動部36由與快門26之至少一部分相同之材料形成。 The second spring 34 faces the first spring 28 on a side farther from the shutter 26 than the first spring 28 . A voltage is applied to the second anchor portion 32, and the first spring 28 is pulled by the second spring 34 by the electrostatic attractive force generated by the potential difference from the first spring 28. If the first spring 28 is pulled, the shutter 26 is also pulled. That is, the first spring 28 and the second spring 34 are configured to constitute the driving portion 36 for mechanically driving the shutter 26. The drive portion 36 is formed of the same material as at least a portion of the shutter 26.

如圖1所示，朝向右側開口RO及左側開口LO之各者之光之通過及遮斷係藉由任一快門26而控制。右側開口RO用之快門26及左側開口LO用之快門26對應於1個像素14，藉由多個像素14而顯示圖像。因此，設置有複數個(多個)快門26。快門26及驅動部36配置於根據通過右側開口RO及左側開口LO之光之有無及出射時間而顯示圖像之顯示區域。 As shown in FIG. 1, the passage and the blocking of light toward each of the right opening RO and the left opening LO are controlled by any shutter 26. The shutter 26 for the right opening RO and the shutter 26 for the left opening LO correspond to one pixel 14, and an image is displayed by the plurality of pixels 14. Therefore, a plurality of shutters (s) 26 are provided. The shutter 26 and the drive unit 36 are disposed in a display area in which an image is displayed in accordance with the presence or absence of light passing through the right opening RO and the left opening LO and the emission time.

根據本實施形態，通過右側開口RO之光與通過左側開口LO之光係沿不同之傾斜方向前進。通過右側開口RO之光進入右眼(自照射光之方向看為左側之眼)，通過左側開口LO之光進入左眼(自照射光之方向看為右側之眼)。且，使人的左右眼辨識不同之二維圖像，且人腦基於該等兩個二維圖像而構築三維空間。藉此，與將視差屏障用液晶面板重疊於液晶顯示面板而成之構造相比可使裝置薄型化，且因未通過液晶故光效率優異，因與用以顯示二維圖像之構造相同故零件個數未增加。 According to the present embodiment, the light passing through the right opening RO and the light passing through the left opening LO are advanced in different oblique directions. The light passing through the right opening RO enters the right eye (the left eye is seen from the direction of the illumination light), and the light passing through the left opening LO enters the left eye (the right eye is seen from the direction of the illumination light). Moreover, the left and right eyes of the person are recognized by different two-dimensional images, and the human brain constructs a three-dimensional space based on the two two-dimensional images. In this way, the device can be made thinner than the structure in which the liquid crystal panel for a parallax barrier is superimposed on the liquid crystal display panel, and the light transmittance is excellent because the liquid crystal is not passed, and the structure for displaying a two-dimensional image is the same. The number of parts has not increased.

第1基板10與第2基板18係藉由圖1所示之密封材料38空開間隔而固定。密封材料38密接於第1基板10與第2基板18彼此之對向面。於第1基板10與第2基板18之間，藉由密封材料38密封空間。於空間內填充 有液體40(例如聚矽氧油等油)。快門26及驅動部36配置於液體40內。藉由液體40可抑制快門26及驅動部36之作動所引起之振動，亦可防止第1彈簧28與第2彈簧34之固著。在第1基板10及第2基板18包含玻璃之情形時，若使用折射率與玻璃相近之液體40，則藉由充滿液體40，可減少第1基板10與第2基板18之界面之光反射。 The first substrate 10 and the second substrate 18 are fixed by being spaced apart from each other by the sealing material 38 shown in FIG. 1 . The sealing material 38 is in close contact with the opposing surface of the first substrate 10 and the second substrate 18. A space is sealed between the first substrate 10 and the second substrate 18 by a sealing material 38. Fill in space There is liquid 40 (such as oil such as polyoxygenated oil). The shutter 26 and the drive unit 36 are disposed in the liquid 40. The liquid 40 can suppress the vibration caused by the actuation of the shutter 26 and the driving portion 36, and can prevent the first spring 28 and the second spring 34 from being fixed. When the first substrate 10 and the second substrate 18 include glass, when the liquid 40 having a refractive index close to that of the glass is used, the light reflection at the interface between the first substrate 10 and the second substrate 18 can be reduced by filling the liquid 40. .

圖4係本發明之實施形態之第1變化例之立體顯示裝置之概略剖面圖。該例中，於同一第2固定開口122朝不同方向行進之光分別通過右側開口RO及左側開口LO。該例中，因通過右側開口RO之光與通過左側開口LO之光亦朝不同之傾斜方向行進，故可使人之左右眼辨識不同之二維圖像。如此，右側開口RO或左側開口LO與第2固定開口122無須一對一對應。 Fig. 4 is a schematic cross-sectional view showing a stereoscopic display device according to a first modification of the embodiment of the present invention. In this example, light traveling in different directions in the same second fixed opening 122 passes through the right opening RO and the left opening LO, respectively. In this example, since the light passing through the right opening RO and the light passing through the left opening LO also travel in different oblique directions, the left and right eyes of the person can be recognized as different two-dimensional images. Thus, the right side opening RO or the left side opening LO does not need to be in one-to-one correspondence with the second fixed opening 122.
