Abstract

The present invention obtains a three-dimensional display device configuration capable of reducing brightness variation when an observer moves by improving the angular dependence of brightness. A three-dimensional display device (1) is provided with a display panel (10), a switching liquid crystal panel (20), a first polarization plate (15), a second polarization plate (24), a position sensor for acquiring position information about an observer, and a control unit for moving a parallax barrier, in which transparent regions and opaque regions are formed periodically along a prescribed alignment direction, along the alignment direction in accordance with the position information and displaying the parallax barrier on the switching liquid crystal panel (20). The widths of the transparent regions are wider than the widths in the alignment direction of the openings of a plurality of pixels (110). The switching liquid crystal panel (20) includes a first substrate (21), a first orientation film (216), a second substrate (22), a second orientation film (226), and a liquid crystal layer (23). The rubbing direction of the first orientation film (216) is parallel to the transmission axis of the first polarization plate (15), and the rubbing direction of the second orientation film (226) is parallel to the transmission axis of the second polarization plate (24).

Description

technical field [0001] The invention relates to a naked-eye stereoscopic display device. Background technique [0002] A parallax barrier system and a lenticular lens system are known as stereoscopic display devices that can be viewed with the naked eye. These three-dimensional display devices use barriers or lenses to separate light, and map different images in the left and right eyes, giving the observer a three-dimensional sense. In recent years, the parallax barrier method and the lenticular lens method of two viewpoints of naked-eye stereoscopic display devices appearing in the market have become mainstream. [0003] These dual-view stereoscopic display devices can obtain good stereoscopic display in the set area, but when the observer moves his head, the image that should be mapped to the right eye and the image that should be mapped to the left eye will mix, resulting in double The mapped phenomenon is called crosstalk, or an image that should be mapped to the right...
