[0047] 1. First Embodiment

[0048] First refer to Figure 1-9 A first embodiment of the present invention is described.

[0049] 1-1. Structure of display device

[0050] figure 1is a view showing the overall configuration of the display device 100 according to the first embodiment of the present invention. Such as figure 1 As shown, the display device 100 includes a display 110 and a parallax barrier 120 .

[0051] The display 110 is a display unit that displays N viewpoint images, which are respectively oriented toward N viewpoints (N is any plural number), using a plurality of pixels having three sub-pixels. For example, the display 110 may be an LCD (Liquid Crystal Display), a PDP (Plasma Display Panel), an organic EL (Electro Luminescence) panel, or the like.

Abstract

The invention relates to a display apparatus which includes a display unit in which sub-pixels are periodically arranged at a first sub-pixel pitch in a first direction of a screen, each pixel is formed by the plurality of sub-pixels, and a plurality of viewpoint images is displayed on a display surface; and a barrier unit in which transmissive sections having a first width in the first direction are periodically arranged. The first width is set to be approximated to a multiple m (where m=1, 2, . . . , N (where N is the number of plurality of viewpoint images)) of the first sub-pixel pitch.

Description

technical field [0001] The present invention relates to display devices, and more particularly, to display devices that directionally separate images by barriers toward multiple viewpoints. Background technique [0002] A display device has been developed in which a barrier including a transmissive portion spatially separates images orientationally toward a plurality of viewpoints, so that a plurality of images each having different viewpoints can be viewed. In such a display device, by setting a plurality of viewpoints including the positions of the left and right eyes of the viewer and reflecting an image oriented toward the viewpoint at the position of the right eye and an image oriented toward the viewpoint at the position of the left eye Parallax between images, viewers can use their naked eyes to view stereoscopic images. Blocking for display devices is specifically called parallax blocking. Furthermore, display devices utilizing parallax blocking can also display pl...
