[2D vertical and horizontal display]
With reference to FIG. 4, a conventional technique (for example, Japanese Patent Application Laid-Open No. 2011-19508) two-dimensional (2D) vertical and horizontal display will be described.

Switching between the formation of the 3D vertical display parallax barrier and the 3D horizontal display parallax barrier is performed based on whether the direction of the screen (not shown) of the display device 300 is vertical or horizontal. In another aspect, a configuration in which a user of the display device 300 forcibly forms a parallax barrier by giving a switching operation to the display device 300 may be used.

  The liquid crystal panel 330 includes four color sub-pixels. Each pixel is defined as one unit such as pixels 410 and 450, for example, and the color components of the four sub-pixels constituting each pixel are different. More specifically, the pixel 410 includes sub-pixels 411, 412, 413, and 414. Pixel 450 includes sub-pixels 451, 452, 453, and 454.

  According to the configuration shown in FIG. 24, when viewed from the viewing direction, the value of one sub-pixel is calculated from the same color components of nine reference source pixels of 3 pixels × 3 pixels in the horizontal and vertical directions. Accordingly, when viewed from the viewing direction, the resolution for each eye is achieved in a pseudo double resolution in both the horizontal and vertical directions compared to the 3D horizontal display (1) shown in FIG. As a result, a resolution four times higher than that of the 3D horizontal display (1) shown in FIG. 10 is realized. As shown in FIG. 24, one sub-pixel of the liquid crystal panel is calculated from the same color components of the original nine pixels, so that the vertical direction as viewed from the viewing direction compared to the 3D horizontal display (1) shown in FIG. The resolution in the direction and the horizontal direction can be pseudo doubled, and the resolution can be increased without missing all the color components of the original image.

<Summary>
In one aspect, display device 300 according to the present embodiment can have the same configuration of subpixels as 2D display (for example, a square of 2 rows × 2 columns) for both 3D vertical display and 3D horizontal display. 3D display can be realized with the same vertical resolution as 2D display.

  In addition, since the 2D display and the 3D display have the same configuration (2 rows × 2 columns square), circuit design is facilitated.

  In another aspect, the display device 300 may include a sub pixel in which one pixel for 2D vertical display and 2D horizontal display is arranged in 1 row × 4 columns or 4 rows × 1 column.

  In another aspect, the display device 300 may include a sub pixel in which one pixel for 3D vertical display and 3D horizontal display is arranged in one row × 4 columns.

  In another aspect, display device 300 can artificially increase the resolution by calculating one subpixel from the same color component of a plurality of pixels.

  In yet another aspect, the shape of the parallax barrier formed in the display device 300 is a linear shape along the horizontal direction or the vertical direction, so that the manufacturing process of the display device 300 is not complicated.

  In addition, since the sub-pixels are square, the appropriate viewing distance is the same in the case of 3D vertical display and 3D horizontal display, so visibility is maintained.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive.
