Abstract

The invention discloses a 3D (three dimensional) display device and a phase delay piece of the 3D display device. The phase delay piece is arranged on an external surface of a polaroid and comprises multiple first phase delay unit lines, multiple second phase delay unit lines and non-phase delay unit lines, wherein the second-phase delay unit lines and the first phase delay unit lines are arranged in a staggering manner, each non-phase delay unit line is arranged between the adjacent first phase delay unit lines and second phase delay unit line; an optical axis of the non-phase delay unit lines are vertical or parallel to a penetrating shaft of the polaroid; and according to the non-phase delay unit lines, the brightness of juncture of a phase delay region can be weakened, and further improve image interference caused by the attaching and the shifting of the phase delay piece can be improved.

Description

【Technical field】 [0001] The invention relates to 3D display technology, in particular to a 3D display device and a phase retarder. 【Background technique】 [0002] Because people's eyes have a certain distance between them, the directions of objects seen by both eyes are not exactly the same. Therefore, the 3D display utilizes the parallax of the two eyes of human beings to provide different images to the two eyes respectively to produce a three-dimensional effect. [0003] refer to figure 1 As shown, an existing 3D imaging system is provided with a phase retardation layer consisting of a patterned half phase retardation layer 90 and a quarter wavelength phase retardation layer 91 on the light exit surface of a liquid crystal display panel. The retarder is used to deliver images with different polarization directions to the viewer. At the same time, the viewer wears polarized glasses 7, so that the left eye receives the image of a single polarization direction, while the r...
