  As described above, in a conventional display device that performs directional display using a display panel having a plurality of pixels and a lighting device having a plurality of light emitting regions, the plurality of pixels are divided into different images. Further, the plurality of pixels are divided into pixel groups including one pixel to which each image is assigned for each image. In this conventional display device, a light emitting area is provided for each pixel group, that is, a light emitting area is provided corresponding to the pixel group.

In such a conventional display device, since the light emitting areas are provided corresponding to the pixel groups, the number of viewing ranges in the directional display corresponds to the number of pixels included in the pixel group. For this reason, in the conventional display device described above, in order to increase or decrease the number of viewing ranges in the directional display, the number of pixels constituting the pixel group may be increased or decreased according to the increase or decrease of the number of viewing ranges.
By the way, it is convenient if the number of viewing ranges in the directional display can be increased or decreased with one display device.

However, in the conventional display device described above, one light emitting area and one pixel group are associated with each other. For this reason, in the conventional display device, if the number of pixels constituting the pixel group is increased or decreased, the correspondence between the light emitting region and the pixel group cannot be obtained.
That is, conventionally, there is a problem that it is difficult to change the number of viewing ranges in the directional display.

  SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as the following forms or application examples.

Different images of h (h is an integer of 2 or more) are assigned to the plurality of pixels, one for each of the h pixels. The plurality of pixels are divided into a plurality of pixel groups each having j pixels (j is an integer of 2 or more) as one pixel group. The light emitting elements are provided corresponding to the pixel groups.
In this electro-optical device, light from the light emitting element reaches j different viewing ranges through j pixels of the pixel group corresponding to the light emitting element. Therefore, for example, when h = j, by assigning each of the h images to each of the h pixels of the pixel group, each of the h images in each of the different h viewing ranges. Each can be displayed. As a result, the electro-optical device can perform directional display.
In this electro-optical device, the light emitting element is controlled independently of each other between a plurality of light emitting elements in a light emitting state in which light is emitted and a stop state in which light emission is stopped. For this reason, the number of viewing ranges in the directional display can be changed by controlling some of the plurality of projecting elements to the projecting state and controlling other projecting elements to the stopped state.

  Application Example 2 In the electro-optical device described above, the plurality of light-emitting elements are controlled to the light-emitting state or the stopped state based on the number of h, respectively. .

  In this application example, each of the plurality of light emitting elements is controlled to the light emitting state or the stopped state based on the number of h. Thereby, the number of viewing ranges in the directional display can be changed according to the number of images.

  Application Example 3 In the above electro-optical device, the plurality of light emitting elements are controlled to the light emitting state when h = j, and the number h−j is satisfied when h> j. Accordingly, an electro-optical device, wherein a part of the plurality of light emitting elements is controlled to the stopped state, and the other light emitting elements are controlled to the light emitting state.

Further, when h> j, a part of the plurality of light emitting elements is controlled to be in a stopped state and the other light emitting elements are controlled to be in a light emitting state according to the number of h−j. Thereby, the number of viewing ranges in the directional display can be increased according to the number of images.

  In this application example, when h = j × k (k is an integer greater than or equal to 2), k−1 light emitting elements are controlled to be stopped for each k light emitting elements. Accordingly, the number of viewing ranges in the directional display can be increased from j to j × k according to the number of j × k images.

  Application Example 5 In the electro-optical device described above, the electro-optical device includes a control unit that controls the light emission state and the stop state of the light emission element for each of the light emission elements.

  The electro-optical device according to this application example includes a control unit that controls a light emission state and a stop state of the light emission element. This control part controls a light emission state and a stop state for every light emission element. Accordingly, a part of the plurality of light emitting elements can be controlled to be in a light emitting state, and other light emitting elements can be controlled in a stopped state, so that the number of viewing ranges in the directional display can be changed.

In this application example, the light emitting element controlled to the light emitting state is controlled to have high light luminance according to the number of h.
In this electro-optical device, the viewing range in the directional display increases as the number of h, that is, the number of images increases. On the other hand, an increase in the viewing range in the directional display means an increase in the number of projecting elements controlled in the stopped state. When the number of light emitting elements controlled to be stopped increases, the image tends to become dark. For this reason, when the number of images increases, the images tend to be dark.
On the other hand, in this application example, as the number of images increases, the luminance of light from the light emitting element increases. For this reason, even if the number of images increases, the images can be easily displayed brightly.

In the transmissive state, the traveling direction of the light is maintained in at least a part of the light from the plurality of light emitting elements. For this reason, the light from the light emitting element reaches j different viewing ranges from each other through j pixels of the pixel group corresponding to the light emitting element. As a result, the directivity of light is maintained in the transmissive state.
On the other hand, in the scattering state, the light directed toward the liquid crystal contains scattered light, so the directivity of the light incident on the liquid crystal is weakened. Thereby, the directivity in display is weakened. As a result, it is possible to easily cancel the directivity display in the scattering state.
That is, with this electro-optical device, it is possible to easily realize directional display and non-directional display with the directional display canceled.

Thereby, for example, in two pixel arrays adjacent to each other in the second direction, the pixel group in one pixel array and the pixel group in the other pixel array are compared with a configuration in which the pixel groups are aligned in the second direction. The resolution in the first direction can be easily increased. Thereby, it is possible to easily increase the definition in display. As a result, display quality in display can be easily improved.

Incident light incident on the polarizing plate 17a from the illumination panel 15 is incident on the liquid crystal 25 as linearly polarized light 207 having a polarization axis along the direction 201a of the transmission axis of the polarizing plate 17a, that is, the Y ′ direction.
When the liquid crystal 25 is off, the linearly polarized light 207 incident on the liquid crystal 25 is directed toward the polarizing plate 17b as linearly polarized light 209 having a polarization axis along the X ′ direction, as shown in FIG. 17A. It is injected. The linearly polarized light 209 emitted toward the polarizing plate 17b passes through the polarizing plate 17b because the direction of the polarization axis is along the direction 201b of the transmission axis of the polarizing plate 17b.

  On the other hand, when the liquid crystal 25 is in the on state, the linearly polarized light 207 is emitted toward the polarizing plate 17b as the linearly polarized light 207 while maintaining the polarization state, as shown in FIG. The linearly polarized light 207 emitted toward the polarizing plate 17b is absorbed by the polarizing plate 17b because the direction of the polarization axis is orthogonal to the direction 201b of the transmission axis of the polarizing plate 17b.

  In the display device 1, light is emitted from the liquid crystal panel 11 toward the display surface 9 when the liquid crystal 25 is in an off state, and light emission from the liquid crystal panel 11 is blocked when the liquid crystal 25 is in an on state. The white (initially “white display”) display mode is used. However, the display mode is not limited to normally white, and so-called normally black (initially “black display” state) can also be adopted.

By the way, in the display device 1, the dispersive liquid crystal panel 13 is interposed between the illumination panel 15 and the liquid crystal panel 11. Light traveling from the illumination panel 15 toward the liquid crystal panel 11 enters the liquid crystal panel 11 after passing through the dispersive liquid crystal panel 13.
In the dispersive liquid crystal panel 13, a difference in refractive index is generated between the liquid crystal 121 and the polymer layer 119 when the liquid crystal 121 is in an off state (FIG. 9). For this reason, when the liquid crystal 121 is in the off state, the light incident on the dispersive liquid crystal panel 13 is emitted as scattered light in a state of being scattered in various directions. In the dispersive liquid crystal panel 13, a state in which incident light is emitted as scattered light is called a scattered state.

On the other hand, when the liquid crystal 121 is in the on state (FIG. 10), the difference in refractive index between the liquid crystal 121 and the polymer layer 119 changes to an extremely small value. For this reason, when the liquid crystal 121 is in the on state, the light incident on the dispersive liquid crystal panel 13 is emitted while maintaining the traveling direction. That is, when the liquid crystal 121 is in the on state, the dispersion-type liquid crystal panel 13 can transmit the incident light while maintaining the traveling direction of the incident light. In the dispersive liquid crystal panel 13, a state in which incident light is transmitted while the incident light traveling direction is maintained is called a transmissive state.
Note that the scattering state and the transmission state of the dispersion-type liquid crystal panel 13 are controlled by a scattering control unit 193 shown in FIG.

As described above, in this embodiment, the EL element 45 (FIG. 13) is provided corresponding to the pixel group 55. When the dispersive liquid crystal panel 13 is in the transmissive state, the light emitted from the EL element 45 enters the liquid crystal panel 11 toward the pixel 7 in the corresponding pixel group 55.
In this case, light incident on the liquid crystal panel 11 from the EL element 45 is emitted from the first pixel 7 ₁ and second pixel 7 ₂ display face 9 through the pixel group 55.
FIG. 18 is a diagram schematically showing a cross section when the liquid crystal panel 11 and the illumination panel 15 are cut along the line II in FIG.
Light 211 emitted toward the display surface 9 side from the EL element 45 via the first pixels 7 _1, as shown in FIG. 18, to a first range 213.
Further, the light 215 emitted toward the display surface 9 side from the EL element 45 via the second pixels 7 _2, to a second range 217.

In the present embodiment, the light 211 emitted from the plurality of first pixels 7 _1, at distance L1, intersect at both ends of the first range 213. A plurality of second pixels 7 ₂ light 215 emitted from at distance L1, intersect at both ends of the second range 217. This can be realized by setting the interval Pa between the EL elements 45 adjacent in the X direction to be longer than the interval Pb between the pixel groups 55 adjacent in the X direction. Thus, it is possible to from within the first range 213, clearness all first pixels 7 _1. Further, it is possible to from inside the second range 217, clearness all of the second pixel 7 _2. As a result, it is possible to easily improve display quality in display.

From the first range 213, the light 211 emitted from the EL element 45 via the first pixels 7 ₁ can be viewed. From the second range 217, the light 215 emitted from the EL element 45 via the second pixels 7 ₂ can be viewed.
When an eye point within the first range 213, a first image formed by the light 211 from the plurality of first pixels 7 ₁ can be viewed. When an eye point within the second range 217, a second image formed by a plurality of second pixels 7 ₂ light 215 from can be viewed.
That is, in the display device 1, the first image can be displayed in the first range 213 and the second image can be displayed in the second range 217. The first range 213 and the second range 217 are different from each other. Thus, the display device 1 can perform directional display in two ranges arranged in the X direction.

Note that the first range 213 and the second range 217 have a range 219 that overlaps each other (hereinafter referred to as the overlapping range 219). From the overlapping range 219, the first image and the second image are visually recognized in a superimposed state.
Only the first image can be visually recognized from the range 213a obtained by removing the overlapping range 219 from the first range 213. Further, only the second image can be visually recognized from the range 217a obtained by removing the overlapping range 219 from the second range 217. The range 213a and the range 217a are referred to as an appropriate viewing range 213a and an appropriate viewing range 217a, respectively.

Also, EL elements 45 located on an extension line obtained by extending any viewpoint and one first pixel 7 ₁ and the line connecting within the first range 213 to the illumination panel 15, the first pixel 7 ₁ Is associated with a pixel group 55 including When viewed from an arbitrary viewpoint within the first range 213, it is associated with each other in the first pixel 7 ₁ and the EL element 45 overlap each other.
Similarly, EL elements 45 located on an extension line obtained by extending the line connecting the arbitrary viewpoint and one second pixel 7 ₂ in the second range 217 to the illumination panel 15, the second pixel 7 ₂ is associated with the pixel group 55 including ₂ . When viewed from an arbitrary viewpoint within the second range 217, it is associated with each other and the second pixel 7 ₂ and EL element 45 overlap each other.
A plurality of pixels 7 associated with one EL element 45 can be regarded as one set of pixel group 55.
The correspondence relationship between the EL element 45 and the pixel group 55 can also be defined by a line segment that virtually extends from the EL element 45 to the first range 213 or the second range 217. A pixel group 55 through which a line segment virtually extending from the EL element 45 to the first range 213 or the second range 217 passes is associated with the EL element 45 that is the starting point of the line segment.

In the display device 1, if the first image and the second image are images captured from different viewpoints, a stereoscopic image can be displayed in a pseudo manner. In this case, for example, if the first image is an image for the left eye and the second image is an image for the right eye, the first image and the second image constitute a parallax image. As a result, display of a pseudo stereoscopic image can be realized.
In the display device 1, if the left eye is positioned within the appropriate viewing range 213a and the right eye is positioned within the appropriate viewing range 217a, the observer can visually recognize the stereoscopic image.

By the way, the display device 1 can also display only one image. In this case, both the first pixel 7 ₁ and second pixel 7 ₂ may be used to display one image. In the display device 1, when only one image is displayed, the dispersion type liquid crystal panel 13 is controlled to a scattering state (FIG. 9) by the scattering control unit 193 (FIG. 16).
In the scattering state, light incident on the dispersion-type liquid crystal panel 13 is emitted as scattered light. For this reason, the directivity of light from the EL element 45 is weakened. Thereby, the directivity in display is weakened. As a result, it is possible to visually recognize one image in a state where the directivity in display is cancelled.
Thus, the display device 1 can realize directional display and non-directional display from which the directional display is canceled.

In the present embodiment, in the directional display, the luminance of the EL element 45 can be controlled for each EL element 45 according to the density of the image. In this case, the luminance of the EL element 45 is controlled to be high according to the lightness and darkness of the image.
This can be realized by the light emission control unit 195 controlling the illumination panel 15 based on the gradation level designated by the image data DATA1 in the control unit 6 shown in FIG. The shading of the image is controlled by the gradation shown in the image data DATA1. In the pixel 7 for which a high gradation level (bright gradation) is designated, the image becomes light. On the other hand, in the pixel 7 for which a low gradation level (dark gradation) is designated, the image becomes dark.

The light emission control unit 195 outputs the image data DATA2 corresponding to the gradation shown in the image data DATA1 to the signal line driver circuit 157.
This makes it easy to match the gradation shown in the image data DATA1 with the light emission luminance of each EL element 45. As a result, the luminance of the EL element 45 can be controlled to be high according to the lightness and darkness of the image.
By controlling the luminance of the EL element 45 to be high in accordance with the lightness and darkness of the image, the difference in lightness and darkness of the image can be emphasized.
When the first image and the second image constitute a parallax image, the depth of the image is enhanced by controlling the luminance of the EL element 45 to be high according to the lightness of the image. Thereby, the stereoscopic effect of a stereoscopic image can be emphasized.

In the directional display, the number of images is not limited to two of the first image and the second image. Four images obtained by adding a third image and a fourth image to these two images may also be employed.
For the four images, the pixel group 55, as shown in FIG. 19 is divided into a first pixel group 55 ₁ and the second pixel group 55 _2.
The first pixel group 55 ₁ and the second pixel group 55 ₂ are alternately arranged in the X direction. The plurality of first pixel group 55 ₁ are arranged in the V direction. ₂ a plurality of second pixel group 55 are also arranged in the V direction. A plurality of first pixel groups 55 ₁ arranged in the V direction constitute _one pixel group array 221 ₁ . A plurality of second pixel groups 55 ₂ arranged in the V direction constitute one pixel group array 221 ₂ .

In the case of four images, the plurality of EL elements 45 include an EL element 45 ₁ corresponding to the _first pixel group 55 ₁ and an EL element corresponding to the second pixel group 55 _{2 as shown} in FIG. 45 ₂ . In FIG. 20, to indicate clearly the structure, it is hatched in the EL element 45 _2.

Of the four images, the first image and the second image are assigned to the _first pixel group 551. In this case, in the first pixel group 55 ₁ , the first image is assigned to the first pixel 7 ₁ , and the second image is assigned to the second pixel 7 ₂ .
In addition, the third image and the fourth image among the four images are assigned to the _second pixel group 552. In this case, in the second pixel group 55 ₂ , the third image is assigned to the first pixel 7 ₁ and the fourth image is assigned to the second pixel 7 ₂ .

In the case of four images, some EL elements 45 among the plurality of EL elements 45 are controlled to be in an illuminated state, and other EL elements 45 are controlled to be in a stopped state. In this case, either the EL element 45 ₁ and the EL element 45 ₂ is controlled to Shako state, a method of controlling the other EL elements 45 ₁ and EL element 45 ₂ in the stop state may be employed. This control can be achieved by the light emission control unit 195 shown in FIG.
In the following, an example will be described in which the EL element 45 ₁ is controlled to be in the emitting state and the EL element 45 ₂ is controlled to be in the stopped state.
FIG. 21 is a diagram schematically showing a cross section when the liquid crystal panel 11 and the illumination panel 15 are cut along the line II in FIG.
Light 211 emitted toward the display surface 9 side through the first pixel 7 ₁ from the EL element 45 ₁ first pixel group 55 _1, as shown in FIG. 21, to a first range 213 .
Similarly, the light 215 emitted from the EL element 45 ₁ toward the display surface 9 side through the second pixel 7 ₂ of the _first pixel group 55 ₁ reaches the second range 217.

Further, the light 223 emitted from the EL element 45 ₁ toward the display surface 9 side through the first pixel 7 ₁ of the _second pixel group 55 ₂ extends into the third range 225.
Similarly, the second pixel 7 ₂ light 227 emitted toward the display surface 9 side through from the EL element 45 ₁ second pixel group 55 ₂ spans the fourth range 229.
From the third range 225, the light 223 emitted from the EL element 45 ₁ through the first pixel 7 ₁ of the _second pixel group 55 ₂ can be visually recognized. From the fourth range 229, the light 227 emitted from the EL element 45 ₁ through the second pixel 7 ₂ of the second pixel group 55 ₂ can be visually recognized.
When an eye point within the third range 225, a third image formed by the light 223 from the plurality of first pixels 7 ₁ can be viewed. When an eye point in the fourth range 229, a fourth image formed by a plurality of second pixels 7 ₂ light 227 from can be viewed.

That is, in the display device 1, the first image is displayed in the first range 213, the second image is displayed in the second range 217, the third image is displayed in the third range 225, Four images can be displayed in the fourth range 229. The first range 213, the second range 217, the third range 225, and the fourth range 229 are different from each other. Thus, the display device 1 can perform directional display in the four ranges arranged in the X direction.
Note that the second range 217 and the third range 225 have an overlapping range 219. Further, both the third range 225 and the fourth range 229 have an overlapping range 219. From the overlapping range 219, it is visually recognized in a state where two images adjacent in the X direction are overlapped.

In the example of the above four images, if display of one of the four images is stopped, three different images can be directionally displayed in three different ranges. Examples of a method for stopping the image display include a method for performing black display and a method for performing white display.
Further, in the above four image examples, if the images are captured from different viewpoints, the pseudo stereoscopic image can be displayed as a stereoscopic image captured from three different directions. In this case, the first image and the second image constitute a set of parallax images, the second image and the third image constitute a set of parallax images, and the third image and the fourth image Constitute a set of parallax images. Thereby, the display of the three-dimensional image captured from three different directions can be realized. Thereby, for example, when the position of the observer with respect to the display device 1 changes, it is possible to give the observer a feeling that the angle of the object of the stereoscopic image continuously changes.

In the display device 1, when the number of images is two, the plurality of EL elements 45 are controlled to be in an illuminated state. When the number of images exceeds two, some of the plurality of EL elements 45 are controlled to be in a stopped state and the other EL elements 45 are controlled to be in a light emitting state according to the number exceeding the number.
Thereby, in the display device 1, the number of viewing ranges in the directional display can be changed according to the number of images.
This can be ruled out as follows, for example.
According to this law, the number of images in the directional display is h (h is an integer of 2 or more), and the number of pixels 7 constituting the pixel group 55 is j (j is an integer of 2 or more and h or less). ).
When h = j, the plurality of EL elements 45 are controlled to be in an illuminated state. When h> j, according to the number of h−j, some of the plurality of EL elements 45 are controlled to be in a stopped state, and the other EL elements 45 are controlled to be in a light emitting state.

Furthermore, the above laws can be developed.
When h = j × k (k is an integer equal to or greater than 2), for each of the plurality of EL elements 45, k−1 EL elements 45 are controlled to be stopped.
In the present embodiment where j = 2, in the example of the four images described above, since h = 4, k = 2. In the example of four images, the number of the EL elements 45 is controlled to be in a stopped state for every k = 2, k−1 = 1. In the example illustrated in FIG. 21, the EL element 45 ₂ is controlled to be in a stopped state among the EL elements 45 ₁ and 45 ₂ .
In the present embodiment in which j = 2, for example, when the number of images is h = 6, k = 3. In the case of h = 6, the plurality of EL elements 45 are controlled so that k−1 = 2 EL elements 45 are stopped every k = 3.
According to this rule, the number of viewing ranges in the directional display can be increased from j to j × k according to the number of h = j × k images.

According to this rule, when the number of viewing ranges is j × k, a maximum of h = j × k images can be directionally displayed. If images that perform black display or white display are included in h = j × k images, fewer than j × k images can be directionally displayed.
Further, even when the number of viewing ranges in the directional display is changed according to the number of images, a method of controlling the luminance of the EL element 45 to be high according to the lightness of the image can be adopted. Thereby, even when the number of viewing ranges in the directional display is changed, the difference in light and shade of the image can be emphasized.

According to the above rule, the number of viewing ranges in the directional display can be increased as the number of h, that is, the number of images increases. On the other hand, an increase in the number of viewing ranges in the directional display means an increase in the number of EL elements 45 controlled to be stopped. When the number of EL elements 45 controlled to be stopped increases, the image tends to become dark. For this reason, when the number of images increases, the images tend to be dark.
On the other hand, in the present embodiment, the EL element 45 controlled to be in the light emission state is controlled to have high emission luminance according to the number of images. This can be achieved by the light emission control unit 195 outputting the image data DATA2 corresponding to the number of images to the signal line drive circuit 157 based on the command of the control unit 6 shown in FIG.
Thereby, even if the number of viewing ranges is increased, it is possible to easily display an image brightly.

As the degree of increasing the light emission luminance, for example, a degree corresponding to the value of the variable k can be adopted.
For example, when k = 2, the plurality of EL elements 45 are controlled to be stopped at a rate of one in two. For this reason, when k = 2, the brightness of the illumination panel 15 is substantially halved compared to when h = 2 and j = 2. Therefore, when the luminance of the EL element 45 controlled to the light emission state is increased by k times when k = 2, the brightness of the illumination panel 15 is made substantially equal to that when h = 2 and j = 2. Can do.
For this reason, it is preferable to control the luminance of the EL element 45 that is controlled to be in the radiant state to k times the luminance according to the value of k.

  Furthermore, even when the luminance of the EL element 45 that is controlled to be in the light-emitting state is controlled to be high according to the number of images, a method of controlling the luminance of the EL element 45 to be high according to the lightness of the image can be adopted. Accordingly, it is possible to emphasize the difference in light and shade of the image while increasing the number of viewing ranges while keeping the image to be displayed bright.

In the present embodiment, the EL element 45 corresponds to an electroluminescence element as a light emitting element, the light emission control unit 195 corresponds to a control unit, and the dispersive liquid crystal 35 corresponds to an optical element. Further, the X direction corresponds to the first direction, the Y direction corresponds to the second direction, and the V direction corresponds to a direction intersecting with both the first direction and the second direction.
In the present embodiment, the number of pixels 7 constituting the pixel group 55 is two (j = 2), but the number of pixels 7 constituting the pixel group 55 is not limited to this. As the number of the pixels 7 constituting the pixel group 55, an arbitrary number of three or more can be adopted.
In the present embodiment, a configuration in which the EL element 45 is provided corresponding to the pixel group 55 is adopted as the configuration of the illumination panel 15, but the configuration of the illumination panel 15 is not limited to this. As the configuration of the illumination panel 15, a configuration in which the EL elements 45 are provided corresponding to the pixels 7 may be employed. Thereby, the number of viewing ranges in the directional display can be finely increased or decreased.

In the present embodiment, the plurality of pixel groups 55 are arranged in both the X direction and the V direction, but the arrangement of the pixel groups 55 is not limited to this. As the arrangement of the pixel group 55, an arrangement in which a plurality of pixel groups 55 are arranged in both the X direction and the Y direction may be employed.
However, in the arrangement in which the plurality of pixel groups 55 are arranged in both the X direction and the V direction, the resolution in the X direction is lower than that in the arrangement in which the plurality of pixel groups 55 are arranged in both the X direction and the Y direction. It can be made easy to increase. Thereby, it is possible to easily increase the definition in display. As a result, display quality in display can be easily improved.

  In the present embodiment, the TN liquid crystal 25 has been described as an example. However, the liquid crystal 25 is not limited to this, but is FFS (Fringe Field Switching), IPS (In Plane Switching), and VA (Vertical Alignment). Various types such as can be adopted.

The display device 1 described above can be applied to, for example, the display unit 510 of the electronic device 500 illustrated in FIG. This electronic device 500 is a display device for a car navigation system. In the electronic device 500, for example, an image such as a map is visually recognized as the first image from the driver's seat side by the display unit 510 to which the display device 1 is applied, and an image such as a movie is displayed as the second image from the passenger seat side. It can be visually recognized.
In electronic device 500, since display device 1 is applied as display unit 510, the number of viewing ranges in the directional display can be easily changed.

The display device 1 can also be applied to, for example, the display unit 610 of the electronic device 600 illustrated in FIG. The electronic device 600 is a mobile phone. This electronic device 600 has operation buttons 611. The display unit 610 can display various information including contents input by the operation buttons 611 and incoming call information.
In the electronic device 600, for example, a pseudo stereoscopic image can be displayed by the display unit 610 to which the display device 1 is applied. In this electronic apparatus 600, since the display device 1 is applied to the display unit 610, the number of viewpoints of the parallax image can be easily increased. If a plurality of images captured from continuously changing viewpoints are employed, pseudo stereoscopic images can be displayed as stereoscopic images captured from different directions. Thereby, when the position of the observer with respect to the display unit 610 changes, it is possible to give the observer a feeling that the angle of the object of the stereoscopic image continuously changes.
The electronic device 500 and the electronic device 600 are not limited to display devices and mobile phones for car navigation systems, but include various electronic devices such as mobile computers, digital still cameras, digital video cameras, in-vehicle devices, and audio devices. It is done.
