Problems solved by technology

[0004] In the above-mentioned stereoscopic display device, if viewed from a certain angle of view from the center of the vertical direction of the stereoscopic display device, a part of the image for the right eye generated by the liquid crystal display panel passes through the 1 / 4 wavelength plate for the left eye, resulting in transmission. Intermodulation distortion to the observer's left eye

Embodiment 1

[0043] As Example 1, the image generation unit 160, the polarizing plate 170, and the polarization axis control plate 180 of the stereoscopic display device 100 have the respective values ​​shown in Table 2 below, and the intermodulation defined by the following formulas (2) to (4) is measured. Distortion rate C(θ). In addition, as Comparative Example 1, using the stereoscopic display device 100 under the same conditions as in the above-mentioned Example 1 except that the polarization axis control plate 180 does not have the light shielding portion 190 , the crossmodulation distortion ratio C(θ) was similarly measured.

[0044] 【Table 2】

[0045]

[0046] C(θ)=(C L (θ)+C R (θ)) / 2 (2)

[0047] C L (θ)=(R wL -B L ) / (L wL -B L )×100% (3)

[0048] C R (θ)=(L wR -B R ) / (R wR -B R )×100% (4)

[0049] Here, B L , is the luminance of the left-eye image light when the right-eye image light and the left-eye image light observed at the viewing angle θ through the left-...

Abstract

The invention provides a stereoscopic displaying apparatus which reduces the intermodulatino distortion. In the stereoscopic displaying apparatus which comprises an image generating region, a polarizing plate and a polarization axis control plate, the polarization axis control plate includes: a right eye polarizing region on which a right eye image light is incident; a left eye polarizing region which is arranged adjacent to the right eye polarizing region and on which a left eye image light is incident; a plurality of light blocking sections arranged on a plane facing the polarizing plate, each of which is a boundary between the right eye polarizing region, and the left eye polarizing region that blocks the right eye image light and the left eye image light; and a plurality of apertures formed between each of the plurality of light blocking sections that transmit therethrough the right eye image light and the left eye image light. The image light emitted from one of the right eye polarizing region and the left eye polarizing region and incident on one of the plurality of apertures goes to the inside of the angle of field while the image light emitted from the other of the right eye polarizing region and the left eye polarizing region adjacent to each other and incident on the one aperture goes to the outside of the angle of field.

Description

technical field [0001] The invention relates to a stereoscopic display device. In particular, the present invention relates to a stereoscopic display device that reduces cross-modulation distortion of left and right eye image lights. Background technique [0002] A known stereoscopic display device is, for example, one described in Patent Document 1, which generates a right-eye image and a left-eye image by utilizing the visual error of the right eye and the left eye, so that the observer can see the stereoscopic view. The stereoscopic display device has a liquid crystal display panel for generating an image for the right eye and an image for the left eye, and is disposed on the viewer side of the liquid display panel, facing an area where the image for the right eye and the image for the left eye are generated, and 1 / 4 wavelength plates with phase advance axes offset from each other by 90 degrees. [0003] Patent Document 1: JP-A-10-253824. [0004] In the above-mentione...
