[0025] [Example of Configuration of Stereoscopic Image Display Device]

[0026] figure 1 It is a view showing an example of the configuration of a stereoscopic image display device of an embodiment of the present disclosure.

[0027] The stereoscopic image display device 11 displays the stereoscopic image and the planar image while switching the display between the three-dimensional stereoscopic image based on the parallax barrier method and the two-dimensional planar image as needed. The stereoscopic image display device 11 is configured to include a display unit 21, a control unit 22 and a parallax barrier driving unit 23.

[0028] The display unit 21 includes a backlight 31, a light modulation panel 32, and a parallax barrier 33, and displays an image including an image for the right eye observed (feeled) by the observer's right eye and an image for the left eye observed by the observer's left eye. Two-dimensional plane image or three-dimensional stereo image.

[0102] [About the configuration of the filter area]

[0103] In addition, although the above describes the case where the light shielding area is provided only on one edge side of the filter area of ​​each sub-pixel in the y direction, the light shielding area may also be provided on both edge sides of the filter area in the y direction.

[0104] In this case, such as Image 6 Shown in for example figure 2 In each sub-pixel of the light modulation panel 32 shown, the light shielding area is set to sandwich the filter area. In addition, Image 6 Middle and figure 2 Corresponding parts in each part are denoted by the same reference numerals, and the description will be omitted appropriately.

[0105] In addition, in Image 6 A part of the light modulation panel 32 and the switching liquid crystal layer 84 are shown in. in Image 6 In, the horizontal direction, the vertical direction, and the depth direction represent the x, y, and z directions, respectively. In addition, ...

[0118] [About the configuration of the filter area]

[0119] Although the case of displaying a stereoscopic image including an image for the left eye and an image for the right eye is described above, the stereoscopic image display device 11 may also display a multi-viewpoint stereoscopic image including a plurality of images of three or more viewpoints.

[0120] In this case, for example, such as Figure 7 As shown, sub-pixels having color filters of each color of R, G, and B are arranged on the filter surface of the light modulation panel 32. In addition, Figure 7 Middle and figure 2 Corresponding parts in each part are denoted by the same reference numerals, and the description will be omitted appropriately. In addition, Figure 7 In, the horizontal, vertical, and depth directions are assumed to be the x, y, and z directions, respectively. In addition, in Figure 7 In the illustrated example, the switching liquid crystal layer 84, that is, the parallax barrier 33 is ...

Abstract

A display device includes: a display unit having a region which emits color light for displaying a stereoscopic image including images of a plurality of viewing points; and a separation unit that separates optically the images of the respective viewing points from each other so that the images of different viewing points are observed by different eyes of a viewer, wherein in a visible region on the display unit in which the image of a predetermined viewing point observed by the viewer is displayed, the region which emits the color light is present at each position of the stereoscopic image in a parallax direction regardless of a viewing position of the viewer who observes the stereoscopic image.

Description

technical field [0001] The present disclosure relates to a display device, and in particular, to a display device capable of suppressing occurrence of moiré. Background technique [0002] In the prior art, there are known display devices that display stereoscopic images using a parallax barrier method, a lenticular method, and the like, without the aid of special glasses. [0003] In such a display device, image display is performed such that images having different viewpoints are observed by different eyes of respective observers. However, in such a display device, since a pixel region of the display device displaying an image and a non-pixel region of the display device not displaying an image are perceived by a viewer, moiré is generated. That is, when the brightness difference between the pixel area and the non-pixel area is large, moiré is generated. [0004] Therefore, there has been proposed a technique for reducing moiré in which, when displaying a stereoscopic ima...
