Definitions
- the present disclosure relates to a display panel capable of multi-view displaying that allows visual recognition of two-dimensional video (planar video) that differs for each point of view or three-dimensional displaying that allows visual recognition of three-dimensional video (stereoscopic video) from a specific point of view. Furthermore, the present disclosure relates to a display device including this display panel and electronic apparatus including this display device.
- a display device having a barrier layer over the display area of a display panel is known.
- a barrier layer in which plural light transmissive slits isolated from each other by a light blocking area are provided is disclosed in Japanese Patent Laid-open No. Hei 9-281440 for example.
- a barrier liquid crystal in which a light blocking area is generated by voltage application to a liquid crystal is disclosed in Japanese Patent Laid-open No. Hei 8-106070 for example.
- the edge of the display area in which plural display pixels are two-dimensionally disposed, needs to be precisely aligned with the edge of the metal frame.
- positioning of the metal frame needs to be performed at the pixel-size level. Therefore, slight dimensional error or position misalignment of the metal frame leads to a possibility that the metal frame covers the display pixel.
- the present disclosure has been made in order to solve the problems described above, and it is therefore desirable to provide a display panel capable of making the black streak inconspicuous, and display device and electronic apparatus including it.
- a display panel including a panel section and a barrier section disposed at a position opposed to the panel section.
- the panel section has a display area in which a plurality of display pixels are two-dimensionally disposed and a ring-like frame area provided at the periphery of the display area.
- the barrier section has a barrier pattern composed of a light blocking area and a light transmissive area. Both the light blocking area and the light transmissive area are disposed in a first area opposed to the display area and a ring-like second area opposed to the frame area.
- a display device including the above-described display panel and a drive section that drives at least the panel section out of the panel section and the barrier section.
- electronic apparatus including the above-described display device.
- both the light blocking area and the light transmissive area of the barrier section are disposed in not only the first area opposed to the display area but also the ring-like second area opposed to the frame area. Due to this feature, in not only the display area but also the frame area, the light blocking area included in the barrier pattern is disposed and the light transmissive area included in the barrier pattern is disposed. As a result, light that is unnecessary for displaying is blocked by the light blocking area included in the barrier pattern in not only the display area but also the frame area. Furthermore, light transmitted through the light transmissive area included in the barrier pattern is output from not only the display area but also the frame area.
- the light transmissive area is disposed at places corresponding to the left and right sides of the display area in the second area for example. Furthermore, according to need, the light transmissive area may be disposed also at places corresponding to the upper and lower sides of the display area in the second area. Part of the plurality of light transmissive slits may be disposed in only the second area in such a manner as not to range over the first area. Furthermore, all or part of the plurality of light transmissive slits may be so disposed as to straddle both the first area and the second area.
- the display area has e.g. a rectangular shape having four sides.
- the light blocking area may be formed of a plurality of light blocking slits extended along a direction parallel to one side of the display area or may be formed of a plurality of light blocking slits extended along a direction intersecting one side of the display area.
- the light blocking area may be formed of a plurality of light blocking slits that are arranged along a first direction intersecting one side of the display area and are arranged also along a second direction intersecting the first direction.
- the barrier section may have a light blocking component in the light blocking area and have an aperture in the light transmissive area. Furthermore, the barrier section may be capable of controlling an optical characteristic of the light blocking area based on a control signal from the external.
- the black streak can be made inconspicuous with prevention of light leakage that leads to displaying failure also when the display panel is so used as to be rotated by 90 degrees for example.

- the kinds and number of colors of the sub-pixels 32 included in the display pixel 31 are not limited to the above description.
- the array of the sub-pixels 32 R, 32 G, and 32 B is also not limited to the above description.
- the barrier section 40 blocks part of light (image light) output from the respective display pixels 31 of the panel section 30 .
- the barrier section 40 is to allow the viewer to visually recognize two-dimensional video (planar video) that differs for each point of view or visually recognize three-dimensional video (stereoscopic video) from a specific point of view by blocking part of the image light. If the barrier section 40 is so configured that the viewer can visually recognize two-dimensional video (planar video) that differs for each point of view, the display device 1 serves as a so-called multi-view display device.

- only one or plural light blocking slits 40 A at both ends of the arrangement direction among the plural light blocking slits 40 A may have a width wider than that of the other light blocking slits 40 A. That is, the respective light blocking slits 40 A may have various shapes and sizes within such a range that the respective light transmissive slits 40 B have the same shape and the same size.
- FIG. 4 schematically shows one example of the sectional configuration along the direction of arrow A-A in FIG. 2 .
- the light blocking slits 40 A and the light transmissive slits 40 B are disposed in the area opposed to the display area 30 A and the ring-like area opposed to the frame area 30 B as shown in FIGS. 2 to 4 .

- the light blocking slits 40 A and the light transmissive slits 40 B are disposed in the area opposed to the display area 30 A and at places corresponding to the left and right sides of the display area 30 A (i.e. partial areas 30 C) in the ring-like area opposed to the frame area 30 B.
- the light blocking slits 40 A and the light transmissive slits 40 B are formed in both the frame exposed area 30 B- 1 and the frame covered area 30 B- 2 as shown in FIG. 4 .
- One light blocking slit 40 A is formed in each of the right-side frame exposed area 30 B- 1 and the left-side frame exposed area 30 B- 1 as shown in FIG. 4 for example.

Furthermore, the light transmissive slit 40 B is so formed as to straddle the frame exposed area 30 B- 1 and the frame covered area 30 B- 2 as shown in FIG. 4 for example. As shown in FIG. 7 , the light blocking slit 40 A may be so formed as to straddle the frame exposed area 30 B- 1 and the frame covered area 30 B- 2 for example.

- light output from the backlight 10 is modulated by the respective display pixels 31 of the panel section 30 and predetermined image light is output to the barrier section 40 . Then, part of the image light is blocked by the light blocking slits 40 A of the barrier section 40 and light transmitted through the light transmissive slits 40 B is output from the video display surface 1 A of the display panel 20 .
- the light output from the video display surface 1 A forms images at plural points of view for example, so that two-dimensional video (planar video) is generated.
- the light output from the video display surface 1 A forms an image at a specific point of view for example, so that three-dimensional video (stereoscopic video) is generated.
- both the light blocking slit 40 A and the light transmissive slit 40 B of the barrier section 40 are disposed in not only the area opposed to the display area 30 A but also the ring-like area opposed to the frame area 30 B. Due to this feature, in not only the display area 30 A but also the frame area 30 B, the light blocking slit 40 A included in the barrier pattern is disposed and the light transmissive slit 40 B included in the barrier pattern is disposed. As a result, light that is unnecessary for displaying is blocked by the light blocking slit 40 A included in the barrier pattern in not only the display area 30 A but also the frame area 30 B. Furthermore, light transmitted through the light transmissive slit 40 B included in the barrier pattern is output from not only the display area 30 A but also the frame area 30 B. Therefore, the black streak can be made inconspicuous with prevention of light leakage that leads to displaying failure.
- each light blocking slit 40 A is formed of e.g. a light blocking component and each light transmissive slit 40 B is e.g. an aperture. That is, the barrier section 40 is based on a static configuration. However, the barrier section 40 may be based on a dynamic configuration in which the optical characteristics of the light blocking slit 40 A can be controlled based on a control signal from the external.
- the barrier section 40 has e.g. a pair of transparent electrode substrates formed of glass or the like including a transparent electrode, and a pair of polarizing plates provided outside the pair of transparent electrode substrates.
- the pair of transparent electrode substrates have alignment films for which alignment treatment is performed in a predetermined direction on their surfaces opposed to each other.
- the barrier section 40 has a liquid crystal layer between the pair of transparent electrode substrates.
- the barrier section 40 has the transparent electrode at the place corresponding to the light blocking slit 40 A and has a transparent electrode that can be driven independently of the former transparent electrode also at the place corresponding to the light transmissive slit 40 B. In this manner, in the present modification example, the barrier section 40 is based on a dynamic configuration and therefore the drive section drives not only the panel section 30 but also the barrier section 40 .
- the present modification example has the same configuration as that of the above-described embodiment regarding the remaining part. Therefore, as with the above-described embodiment, the black streak can be made inconspicuous with prevention of light leakage that leads to displaying failure.
- the barrier pattern is extended along the vertical direction. However, it may be extended along an oblique direction for example.
- the light blocking slit 40 A and the light transmissive slit 40 B may be extended along a direction intersecting the vertical direction (i.e. oblique direction).
- FIG. 8 shows one example of the planar configuration of the barrier section 40 according to the present modification example together with the panel section 30 .
- part of the light blocking slits 40 A is so disposed as to straddle both the display area 30 A and the frame area 30 B.
- part of the light transmissive slits 40 B is also so disposed as to straddle both the display area 30 A and the frame area 30 B.
- the barrier pattern is extended along the vertical direction or an oblique direction.
- a step barrier pattern may be employed.
- the step barrier pattern refers to e.g. a pattern in which, as shown in FIG. 9 , the plural light transmissive slits 40 B are arranged along a direction intersecting one side of the display area 30 A (or the panel section 30 ) and arranged also along a direction intersecting this arrangement direction.
- FIG. 9 shows one example of the planar configuration of the barrier section 40 according to the present modification example together with the panel section 30 .
- the light blocking slit 40 A and the light transmissive slit 40 B may be disposed in not only the display area 30 A and the partial area 30 C but also the partial area 30 D as shown in FIGS. 10 to 13 for example.
- FIG. 10 shows one modification example of the planar configuration of the barrier section 40 according to the above-described second modification example.
- FIG. 11 shows one example of the sectional configuration along the direction of arrow A-A in FIG. 10 .
- FIG. 12 shows one modification example of the planar configuration of the barrier section 40 according to the above-described third modification example.
- FIG. 13 shows one example of the sectional configuration along the direction of arrow A-A in FIG. 12 .
- the light blocking slit 40 A and the light transmissive slit 40 B may be disposed in the display area 30 A and the partial areas 30 C and 30 D.
- the black streak can be made inconspicuous with prevention of light leakage that leads to displaying failure.
- the barrier section 40 may be disposed under the panel section 30 (i.e. between the panel section 30 and the backlight 10 ) as shown in FIG. 14 for example. Also in this case, the black streak can be made inconspicuous with prevention of light leakage that leads to displaying failure.

Description
- This application is a continuation of U.S. patent application Ser. No. 13/414,809 filed Mar. 8, 2012, the entirety of which is incorporated herein by reference to the extent permitted by law. The present application claims the benefit of priority to Japanese Patent Application No. JP 2011-068154 filed on Mar. 25, 2011 in the Japan Patent Office, the entirety of which is incorporated by reference herein to the extent permitted by law.
- The present disclosure relates to a display panel capable of multi-view displaying that allows visual recognition of two-dimensional video (planar video) that differs for each point of view or three-dimensional displaying that allows visual recognition of three-dimensional video (stereoscopic video) from a specific point of view. Furthermore, the present disclosure relates to a display device including this display panel and electronic apparatus including this display device.
- In recent years, display devices capable of multi-view displaying or three-dimensional displaying have been put into practical use. As one of such display devices, e.g. a display device having a barrier layer over the display area of a display panel is known. As one of such barrier layers, a barrier layer in which plural light transmissive slits isolated from each other by a light blocking area are provided is disclosed in Japanese Patent Laid-open No. Hei 9-281440 for example. Furthermore, a barrier liquid crystal in which a light blocking area is generated by voltage application to a liquid crystal is disclosed in Japanese Patent Laid-open No. Hei 8-106070 for example.
- If the above-described barrier layer is provided, light leakage readily occurs from the periphery of the barrier layer. As a countermeasure against this problem, covering the periphery of the barrier layer by the metal frame of the chassis will be possible for example. To obtain this structure, the edge of the display area, in which plural display pixels are two-dimensionally disposed, needs to be precisely aligned with the edge of the metal frame. However, for this precise alignment, positioning of the metal frame needs to be performed at the pixel-size level. Therefore, slight dimensional error or position misalignment of the metal frame leads to a possibility that the metal frame covers the display pixel.
- In addition, a method of enlarging the outer periphery of the barrier layer to the area where light leakage occurs to prevent the light leakage will be possible for example. Normally, the metal frame has a size somewhat larger than the display area in view of dimensional error and position misalignment. Therefore, if the outer periphery of the barrier layer is enlarged as described above, the light blocking area of the barrier layer is located between the metal frame and the display area and thus the light blocking area often looks like a black streak. In particular, if the metal frame is decorated with a bright color such as white, this black streak is conspicuous and is possibly regarded as displaying failure.
- The present disclosure has been made in order to solve the problems described above, and it is therefore desirable to provide a display panel capable of making the black streak inconspicuous, and display device and electronic apparatus including it.
- According to an embodiment of the present disclosure, there is provided a display panel including a panel section and a barrier section disposed at a position opposed to the panel section. The panel section has a display area in which a plurality of display pixels are two-dimensionally disposed and a ring-like frame area provided at the periphery of the display area. The barrier section has a barrier pattern composed of a light blocking area and a light transmissive area. Both the light blocking area and the light transmissive area are disposed in a first area opposed to the display area and a ring-like second area opposed to the frame area.
- According to another embodiment of the present disclosure, there is provided a display device including the above-described display panel and a drive section that drives at least the panel section out of the panel section and the barrier section. According to another embodiment of the present disclosure, there is provided electronic apparatus including the above-described display device.
- In the display panel, the display device, and the electronic apparatus according to the embodiments of the present disclosure, both the light blocking area and the light transmissive area of the barrier section are disposed in not only the first area opposed to the display area but also the ring-like second area opposed to the frame area. Due to this feature, in not only the display area but also the frame area, the light blocking area included in the barrier pattern is disposed and the light transmissive area included in the barrier pattern is disposed. As a result, light that is unnecessary for displaying is blocked by the light blocking area included in the barrier pattern in not only the display area but also the frame area. Furthermore, light transmitted through the light transmissive area included in the barrier pattern is output from not only the display area but also the frame area.
- In the display panel, the display device, and the electronic apparatus according to the embodiments of the present disclosure, the light transmissive area is formed of e.g. a plurality of light transmissive slits. In this case, the plurality of light transmissive slits are disposed regularly as a whole, and the respective light transmissive slits have the same shape and the same size for example.
- The light transmissive area is disposed at places corresponding to the left and right sides of the display area in the second area for example. Furthermore, according to need, the light transmissive area may be disposed also at places corresponding to the upper and lower sides of the display area in the second area. Part of the plurality of light transmissive slits may be disposed in only the second area in such a manner as not to range over the first area. Furthermore, all or part of the plurality of light transmissive slits may be so disposed as to straddle both the first area and the second area.
- The display area has e.g. a rectangular shape having four sides. In this case, the light blocking area may be formed of a plurality of light blocking slits extended along a direction parallel to one side of the display area or may be formed of a plurality of light blocking slits extended along a direction intersecting one side of the display area. Alternatively, the light blocking area may be formed of a plurality of light blocking slits that are arranged along a first direction intersecting one side of the display area and are arranged also along a second direction intersecting the first direction.
- The barrier section may have a light blocking component in the light blocking area and have an aperture in the light transmissive area. Furthermore, the barrier section may be capable of controlling an optical characteristic of the light blocking area based on a control signal from the external.
- In the display panel, the display device, and the electronic apparatus according to the embodiments of the present disclosure, light that is unnecessary for displaying is blocked by the light blocking area included in the barrier pattern in not only the display area but also the frame area. Furthermore, light transmitted through the light transmissive area included in the barrier pattern is output from not only the display area but also the frame area. Therefore, the black streak can be made inconspicuous with prevention of light leakage that leads to displaying failure.
- If the light transmissive area is disposed at not only the places corresponding to the left and right sides of the display area but also the places corresponding to the upper and lower sides of the display area in the second area in the embodiments of the present disclosure, the black streak can be made inconspicuous with prevention of light leakage that leads to displaying failure also when the display panel is so used as to be rotated by 90 degrees for example.

FIG. 1A shows one example of the sectional configuration of adisplay device 1 according to one embodiment of the present disclosure.FIG. 1B shows one example of the upper surface configuration of thedisplay device 1 ofFIG. 1 .FIGS. 1A and 1B are schematic diagrams and the dimensions and shapes in these diagrams are not necessarily the same as the actual dimensions and shapes. Thedisplay device 1 includes adisplay panel 20 and abacklight 10 disposed on the back side of thedisplay panel 20. Thisdisplay device 1 further includes achassis 50 that houses thedisplay panel 20 and thebacklight 10, and a drive section (not shown) that drives the display panel 20 (specifically, apanel section 30 to be described later). - The
backlight 10 is a surface emission source that illuminates thedisplay panel 20 from the back side. Thechassis 50 has anaperture 50A at the part opposed to the upper surface of thedisplay panel 20 as avideo display surface 1A. The edge of theaperture 50A is disposed in the area opposed to aframe area 30B to be described later. Thedisplay panel 20 has thepanel section 30 and abarrier section 40. The upper surface of thedisplay panel 20 serves as thevideo display surface 1A and thebarrier section 40 is disposed at the surface on the side of thevideo display surface 1A. - The
panel section 30 is a transmissive panel in which the respective display pixels 31 (seeFIG. 1B to be described later) are driven in accordance with a video signal input from the external. Thepanel section 30 is e.g. a liquid crystal panel, an organic electro-luminescence (EL) panel, or a plasma panel. Thepanel section 30 has e.g. a rectangular shape having four sides as shown inFIG. 1B . The following various descriptions are based on the assumption that two sides opposed to each other among four sides of thepanel section 30 are oriented in the horizontal direction and the remaining two sides are oriented in the vertical direction. - The
panel section 30 has adisplay area 30A in which theplural display pixels 31 are two-dimensionally disposed, and the ring-like frame area 30B at the periphery of thedisplay area 30A. Thedisplay area 30A has e.g. a rectangular shape having four sides similarly to thepanel section 30 as shown inFIG. 1B . Hereinafter, the partial places of theframe area 30B opposed to each other in the horizontal direction (left-right direction ofFIG. 1B ) with the intermediary of thedisplay area 30A will be referred to as thepartial area 30C. Furthermore, the partial places of theframe area 30B opposed to each other in the vertical direction (upward-downward direction ofFIG. 1B ) with the intermediary of thedisplay area 30A will be referred to as thepartial area 30D. - The
frame area 30B can be divided into two areas based on the relationship with theaperture 50A of thechassis 50. For example, as shown inFIG. 1B , theframe area 30B is composed of a ring-like frame exposedarea 30B-1 exposed in theaperture 50A and a ring-like frame coveredarea 30B-2 covered by thechassis 50. The frame exposedarea 30B-1 is disposed on the side of thedisplay area 30A and the frame coveredarea 30B-2 is disposed at the periphery of the frame exposedarea 30B-1. Theframe area 30B is covered by a black 33 having light blocking capability as shown inFIG. 4 to be described later. The black 33 is disposed also among thedisplay pixels 31 for example although not shown in the diagram. - Each
display pixel 31 provided in thedisplay area 30A is composed ofplural sub-pixels 32. For example, as shown inFIG. 1B , thedisplay pixel 31 is composed of a sub-pixel 32R for red, a sub-pixel 32G for green, and a sub-pixel 32B for blue. The sub-pixels 32R of therespective display pixels 31 are disposed on one row along the vertical direction (upward-downward direction ofFIG. 1B ) for example. Similarly, the sub-pixels 32G of therespective display pixels 31 are also disposed on one row along the vertical direction (upward-downward direction ofFIG. 1B ) for example, and the sub-pixels 32B of therespective display pixels 31 are also disposed on one row along the vertical direction (upward-downward direction ofFIG. 1B ) for example. That is, the sub-pixels 32R, 32G, and 32B are based on a so-called stripe array. The kinds and number of colors of the sub-pixels 32 included in thedisplay pixel 31 are not limited to the above description. The array of the sub-pixels 32R, 32G, and 32B is also not limited to the above description. - The
barrier section 40 blocks part of light (image light) output from therespective display pixels 31 of thepanel section 30. Thebarrier section 40 is to allow the viewer to visually recognize two-dimensional video (planar video) that differs for each point of view or visually recognize three-dimensional video (stereoscopic video) from a specific point of view by blocking part of the image light. If thebarrier section 40 is so configured that the viewer can visually recognize two-dimensional video (planar video) that differs for each point of view, thedisplay device 1 serves as a so-called multi-view display device. If thebarrier section 40 is so configured as to allow visual recognition of three-dimensional video (stereoscopic video) from a specific point of view, thedisplay device 1 serves as a three-dimensional video display device. - For example, as shown in
FIG. 2 , thebarrier section 40 is disposed at a position opposed to thepanel section 30 and has a barrier pattern composed of light blocking slits 40A and light transmissive slits 40B. The light blocking slit 40A is equivalent to one specific example of the light blocking area set forth in the scope of claims. Thelight transmissive slit 40B is equivalent to one specific example of the light transmissive area set forth in the scope of claims. - Each light blocking slit 40A is formed of e.g. a light blocking component. The plural light blocking slits 40A are disposed regularly as a whole. The respective light blocking slits 40A have the same shape and the same size as shown in
FIG. 2 for example. Eachlight transmissive slit 40B is e.g. an aperture. The plural light transmissive slits 40B are disposed regularly as a whole. The respective light transmissive slits 40B have the same shape and the same size as shown inFIG. 2 for example. - For example, as shown in
FIG. 2 , the plural light blocking slits 40A are extended along the upward-downward direction (vertical direction) ofFIG. 2 and disposed on one row along the left-right direction (horizontal direction) ofFIG. 2 . Similarly, the light transmissive slits 40B are extended along the upward-downward direction (vertical direction) ofFIG. 2 and disposed on one row along the left-right direction (horizontal direction) ofFIG. 2 as shown inFIG. 2 for example. Each light blocking slit 40A is so disposed as not to straddle both thedisplay area 30A and theframe area 30B. That is, some light blocking slits 40A are disposed in only thedisplay area 30A, and the other light blocking slits 40A are disposed in only theframe area 30B. In contrast, some light transmissive slits 40B are so disposed as not to straddle both thedisplay area 30A and theframe area 30B, and the other light transmissive slits 40B are so disposed as to straddle both thedisplay area 30A and theframe area 30B. The light blocking slits 40A and the light transmissive slits 40B are alternately disposed in the arrangement direction as shown inFIG. 2 for example. - All light blocking slits 40A do not need to have the same shape and the same size. For example, as shown in
FIG. 3 , only one or plural light blocking slits 40A at both ends of the arrangement direction among the plural light blocking slits 40A may have a width wider than that of the other light blocking slits 40A. That is, the respectivelight blocking slits 40A may have various shapes and sizes within such a range that the respective light transmissive slits 40B have the same shape and the same size. -
FIG. 4 schematically shows one example of the sectional configuration along the direction of arrow A-A inFIG. 2 . The light blocking slits 40A and the light transmissive slits 40B are disposed in the area opposed to thedisplay area 30A and the ring-like area opposed to theframe area 30B as shown inFIGS. 2 to 4 . That is, the light blocking slits 40A and the light transmissive slits 40B are disposed in not only the area opposed to thedisplay area 30A but also the ring-like area opposed to theframe area 30B. - The light blocking slits 40A and the light transmissive slits 40B are disposed in the area opposed to the
display area 30A and at places corresponding to the left and right sides of thedisplay area 30A (i.e.partial areas 30C) in the ring-like area opposed to theframe area 30B. The light blocking slits 40A and the light transmissive slits 40B are formed in both the frame exposedarea 30B-1 and the frame coveredarea 30B-2 as shown inFIG. 4 . - One light blocking slit 40A is formed in each of the right-side frame exposed
area 30B-1 and the left-side frame exposedarea 30B-1 as shown inFIG. 4 for example. As shown inFIG. 5 , two or more light blocking slits 40A may be formed in each of the right-side frame exposedarea 30B-1 and the left-side frame exposedarea 30B-1 for example. One light blocking slit 40A is formed in each of the right-side frame coveredarea 30B-2 and the left-side frame coveredarea 30B-2 as shown inFIG. 4 for example. As shown inFIG. 6 , the light blocking slit 40A may be absent in the right-side and left-side frame coveredarea 30B-2 for example. Although not shown in the diagram, two or more light blocking slits 40A may be formed in each of the right-side frame coveredarea 30B-2 and the left-side frame coveredarea 30B-2 for example. - The
light transmissive slit 40B is so formed as to straddle thedisplay area 30A and the frame exposedarea 30B-1 as shown inFIG. 4 for example. Furthermore, thelight transmissive slit 40B is so formed as to straddle the frame exposedarea 30B-1 and the frame coveredarea 30B-2 as shown inFIG. 4 for example. As shown inFIG. 7 , the light blocking slit 40A may be so formed as to straddle the frame exposedarea 30B-1 and the frame coveredarea 30B-2 for example. In this case, the light transmissive slit 40B may be formed in the frame exposedarea 30B-1 so as not to straddle the frame exposedarea 30B-1 and the frame coveredarea 30B-2. - In the present embodiment, light output from the
backlight 10 is modulated by therespective display pixels 31 of thepanel section 30 and predetermined image light is output to thebarrier section 40. Then, part of the image light is blocked by the light blocking slits 40A of thebarrier section 40 and light transmitted through the light transmissive slits 40B is output from thevideo display surface 1A of thedisplay panel 20. The light output from thevideo display surface 1A forms images at plural points of view for example, so that two-dimensional video (planar video) is generated. Alternatively, the light output from thevideo display surface 1A forms an image at a specific point of view for example, so that three-dimensional video (stereoscopic video) is generated. - In the present embodiment, both the light blocking slit 40A and the light transmissive slit 40B of the
barrier section 40 are disposed in not only the area opposed to thedisplay area 30A but also the ring-like area opposed to theframe area 30B. Due to this feature, in not only thedisplay area 30A but also theframe area 30B, the light blocking slit 40A included in the barrier pattern is disposed and the light transmissive slit 40B included in the barrier pattern is disposed. As a result, light that is unnecessary for displaying is blocked by the light blocking slit 40A included in the barrier pattern in not only thedisplay area 30A but also theframe area 30B. Furthermore, light transmitted through the light transmissive slit 40B included in the barrier pattern is output from not only thedisplay area 30A but also theframe area 30B. Therefore, the black streak can be made inconspicuous with prevention of light leakage that leads to displaying failure. - In the above-described embodiment, each light blocking slit 40A is formed of e.g. a light blocking component and each
light transmissive slit 40B is e.g. an aperture. That is, thebarrier section 40 is based on a static configuration. However, thebarrier section 40 may be based on a dynamic configuration in which the optical characteristics of the light blocking slit 40A can be controlled based on a control signal from the external. - The
barrier section 40 has e.g. a pair of transparent electrode substrates formed of glass or the like including a transparent electrode, and a pair of polarizing plates provided outside the pair of transparent electrode substrates. The pair of transparent electrode substrates have alignment films for which alignment treatment is performed in a predetermined direction on their surfaces opposed to each other. Thebarrier section 40 has a liquid crystal layer between the pair of transparent electrode substrates. Thebarrier section 40 has the transparent electrode at the place corresponding to thelight blocking slit 40A and has a transparent electrode that can be driven independently of the former transparent electrode also at the place corresponding to the light transmissive slit 40B. In this manner, in the present modification example, thebarrier section 40 is based on a dynamic configuration and therefore the drive section drives not only thepanel section 30 but also thebarrier section 40. - Except for that the
barrier section 40 is based on a dynamic configuration, the present modification example has the same configuration as that of the above-described embodiment regarding the remaining part. Therefore, as with the above-described embodiment, the black streak can be made inconspicuous with prevention of light leakage that leads to displaying failure. - In the above-described embodiment, the barrier pattern is extended along the vertical direction. However, it may be extended along an oblique direction for example. For example, as shown in
FIG. 8 , the light blocking slit 40A and the light transmissive slit 40B may be extended along a direction intersecting the vertical direction (i.e. oblique direction).FIG. 8 shows one example of the planar configuration of thebarrier section 40 according to the present modification example together with thepanel section 30. - In the present modification example, part of the
light blocking slits 40A is so disposed as to straddle both thedisplay area 30A and theframe area 30B. Similarly, part of the light transmissive slits 40B is also so disposed as to straddle both thedisplay area 30A and theframe area 30B. - Also in the present modification example, as with the above-described embodiment, light that is unnecessary for displaying is blocked by the light blocking slit 40A included in the barrier pattern in not only the
display area 30A but also theframe area 30B. Furthermore, light transmitted through the light transmissive slit 40B included in the barrier pattern is output from not only thedisplay area 30A but also theframe area 30B. Therefore, the black streak can be made inconspicuous with prevention of light leakage that leads to displaying failure. - In the above-described embodiment, the barrier pattern is extended along the vertical direction or an oblique direction. However, e.g. a step barrier pattern may be employed. The step barrier pattern refers to e.g. a pattern in which, as shown in
FIG. 9 , the plural light transmissive slits 40B are arranged along a direction intersecting one side of thedisplay area 30A (or the panel section 30) and arranged also along a direction intersecting this arrangement direction.FIG. 9 shows one example of the planar configuration of thebarrier section 40 according to the present modification example together with thepanel section 30. - Also in the present modification example, as with the above-described embodiment, light that is unnecessary for displaying is blocked by the light blocking slit 40A included in the barrier pattern in not only the
display area 30A but also theframe area 30B. Furthermore, light transmitted through the light transmissive slit 40B included in the barrier pattern is output from not only thedisplay area 30A but also theframe area 30B. Therefore, the black streak can be made inconspicuous with prevention of light leakage that leads to displaying failure. - In the above-described second modification example and third modification example, the light blocking slit 40A and the light transmissive slit 40B may be disposed in not only the
display area 30A and thepartial area 30C but also thepartial area 30D as shown inFIGS. 10 to 13 for example.FIG. 10 shows one modification example of the planar configuration of thebarrier section 40 according to the above-described second modification example.FIG. 11 shows one example of the sectional configuration along the direction of arrow A-A inFIG. 10 .FIG. 12 shows one modification example of the planar configuration of thebarrier section 40 according to the above-described third modification example.FIG. 13 shows one example of the sectional configuration along the direction of arrow A-A inFIG. 12 . - Like in the present modification example, the light blocking slit 40A and the light transmissive slit 40B may be disposed in the
display area 30A and thepartial areas panel section 30 is so used as to be rotated by 90 degrees, the black streak can be made inconspicuous with prevention of light leakage that leads to displaying failure. - In the above-described embodiment and first to fourth modification examples, the
barrier section 40 may be disposed under the panel section 30 (i.e. between thepanel section 30 and the backlight 10) as shown inFIG. 14 for example. Also in this case, the black streak can be made inconspicuous with prevention of light leakage that leads to displaying failure. - One application example of the
display device 1 according to the above-described embodiment and modification examples thereof will be described below.FIG. 15 is a perspective view showing one example of the schematic configuration ofelectronic apparatus 100 according to the present application example. Theelectronic apparatus 100 is a cellular phone and includes e.g. amain body section 111 and adisplay body section 112 provided for themain body section 111 openably and closably as shown inFIG. 15 . Themain body section 111 hasoperation buttons 115 and amouthpiece 116. Thedisplay body section 112 has adisplay device 113 and areceiver 117. Thedisplay device 113 displays various kinds of information relating to telephone communication on adisplay screen 114 of thedisplay device 113. Theelectronic apparatus 100 includes a control section (not shown) for controlling the operation of thedisplay device 113. This control section is provided inside themain body section 111 or thedisplay body section 112 as part of a control section responsible for control of the wholeelectronic apparatus 100 or separately from this control section. - The
display device 113 has the same configuration as that of thedisplay device 1 according to the above-described embodiment and modification examples thereof. Thus, in thedisplay device 113, the black streak can be made inconspicuous with prevention of light leakage that leads to displaying failure. - Examples of the electronic apparatus to which the
display device 1 according to the above-described embodiment and modification examples thereof can be applied include, besides the above-described cellular phone, personal computer, liquid crystal television, video tape recorder of a view finder type or monitor direct viewing type, car navigation device, pager, electronic notebook, calculator, word processor, work station, video phone, and POS terminal. - The present disclosure contains subject matter related to that disclosed in Japanese Priority Patent Application JP 2011-068154 filed in the Japan Patent Office on Mar. 25, 2011, the entire content of which is hereby incorporated by reference.
- It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and alterations may occur depending on design requirements and other factors insofar as they are within the scope of the appended claims or the equivalents thereof.
