Description

  The present invention relates to an electro-optical device and an electronic apparatus.

  2. Description of the Related Art Conventionally, as one electro-optical device, a display device that can display a different image for each viewing direction (hereinafter referred to as directional display) when viewed from a plurality of directions is known. As such a display device, there is a display device that can display different images at each of a plurality of viewpoints through a barrier having an opening and a light shielding portion (see, for example, Patent Document 1).

Japanese Patent No. 3096613 (page 2, FIG. 21)

  Here, a mechanism for performing directional display in two directions on a display device having a display panel for forming an image and the above-described barrier will be described with reference to cross-sectional views. As shown in FIG. 30A, the display panel 600 includes a first pixel 601 that displays a first image and a second pixel 603 that displays a second image. An opening 607 is provided in a region overlapping the first pixel 601 and the second pixel 603 in the barrier 605 that is overlaid on the display panel 600. A light shielding part 609 is located between the adjacent openings 607. Light from the lighting device 610 is incident on the first pixel 601 and the second pixel 603 through the opening 607 of the barrier 605.

  The light that enters the first pixel 601 through the opening 607 reaches the first range 611. In addition, light incident on the second pixel 603 through the opening 607 reaches the second range 613. That is, the first image can be viewed from the viewpoint within the first range 611, and the second image can be viewed from the viewpoint within the second range 613. Note that the first range 611 and the second range 613 have a range 615 that overlaps each other. From the viewpoint within the range 615, the first image and the second image are visually recognized in a superimposed state.

From the viewpoint within the range 619a excluding the range 615 from the first range 611, only the first image can be viewed. Similarly, only the second image can be viewed from the viewpoint within the range 619b excluding the range 615 from the second range 613. The range 619a and the range 619b are referred to as an appropriate viewing range 619a and an appropriate viewing range 619b, respectively.
Here, the suitable viewing range 619a and the suitable viewing range 619b can be enlarged by reducing the distance t between the display panel 600 and the barrier 605, as shown in FIG.

By the way, in many cases, a display panel on which barriers are superimposed has a configuration in which a display element is interposed between a pair of glass substrates. In order to expand the viewing range with such a configuration, the glass substrate on the side where the barriers are superimposed must be thinned. However, reducing the thickness of the glass substrate leads to many adverse effects such as a decrease in yield, an increase in manufacturing time, and a decrease in quality due to a decrease in substrate strength.
That is, the conventional display device has an unsolved problem that it is difficult to expand the appropriate viewing range.

  In the display device 10, each region surrounded by the light absorption layer 57 is not defined as the region of the pixel 3. In the display device 10, the region of the pixel 3 is defined as a region where the counter electrode 63 and each pixel electrode 77 overlap in plan view. This is because each region surrounded by the light absorption layer 57 extends between two pixel electrodes 77 adjacent to each other in the X direction as shown in FIG. 14 which is a cross-sectional view taken along line FF in FIG.

By the way, if the 2nd light shielding film 161 shown in FIG. 21 is added to the display surface 7 side of the some pixel 3 with respect to each of the display apparatuses 1, 10, 100, and 200, a 1st image and 2nd will be demonstrated. The range 117 (see FIG. 10) where the image of the image overlaps can be eliminated. In this case, the second light-shielding film 161 has an opening 163 at a portion overlapping the second pixel 3 ₂ and the first pixel 3 ₁ adjacent to each other between the pixel groups 43 adjacent in the X direction in plan view. Is provided. A light shielding portion 165 is formed between the openings 163 adjacent in the X direction.

  In the display devices 1, 10, 100, 200, and 300, the case where each reflection unit 27 is provided independently for each reflection unit 27 between the plurality of reflection units 27 is described as an example. The configuration of the unit 27 is not limited to this. For example, the configuration of the plurality of reflecting portions 27 is based on a reflective film 181 provided in a state in which the plurality of reflecting portions 27 are arranged in series as shown in FIG. Alternatively, a configuration in which the light shielding film 89 is provided on the display surface 7 side may be employed. In this case, in the series of reflection films 181, the portions between the light shielding films 89 function as the reflection portions 27.

  Further, in the display devices 1, 10, 100, 200, and 300, as shown in FIG. 24, a configuration in which each reflecting portion 27 is formed in a convex shape that protrudes toward the plurality of pixels 3 may be employed.

The second reflecting surface 183b reflects a second direction the light from the external light and the light source unit 133 through the second pixel 3 _2. Thereby, it is possible to easily concentrate the light reflected by each reflecting portion 27 on the first pixel 3 ₁ or the second pixel 3 ₂ . For this reason, it can suppress that the light reflected by each reflection part 27 goes to the light absorption layer 57 etc. which are located between the pixels 3, etc., and can improve the utilization efficiency of light.

As described above, each reflecting portion 27 is not limited to this. As shown in FIG. 26, each reflection unit 27 may have an independent configuration for each pixel group 43.

  Further, in the display devices 1, 10, 100, 200, and 300, the TN liquid crystal 25 has been described as an example. However, the liquid crystal 25 is not limited to this, but FFS (Fringe Field Switching) type, IPS (In Plane Switching). Various types such as a type and a VA (Vertical Alignment) type can be adopted.

As described above, the arrangement of the plural pixel groups 43 is not limited to this. As the arrangement of the plurality of sets of pixel groups 43, for example, as shown in FIG. 27, an arrangement arranged in a zigzag manner in the Y direction may be employed. In the arrangement shown in FIG. 27, the first pixels 3 ₁ and the second pixels 3 ₂ shown in FIG. 4 are alternately arranged in the X direction and are also arranged in the Y direction. In this case, each reflecting portion 27 is provided for each pixel group 43 as shown in FIG.

Each of the display devices 1, 10, 100, 200, and 300 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.
