A passive polarized three-dimensional display device and manufacturing method thereof

Abstract

A polarization-type three-dimensional display device and a manufacturing method thereof are provided. The polarization-type three-dimensional display device comprises a liquid crystal panel, which comprises an array substrate and a color filter substrate disposed opposite to each other, the color filter substrate including a plurality of black matrix strips disposed on a side of it facing the array substrate; and a liquid crystal layer, located between the array substrate and the color filter substrate; a phase difference structure, located on a light-exiting side of the liquid crystal panel, wherein a plurality of patterned phase difference diaphragms are arranged on the phase difference structure; a plurality of light-shielding strips, disposed on a side of the array substrate far away from the liquid crystal layer, wherein, orthographic projections of the plurality of light-shielding strips on the phase difference structure cover boundary lines of the patterned phase difference diaphragms on the phase difference structure, and orthographic projections of the plurality of black matrix strips on the phase difference structure cover boundary lines of the patterned phase difference diaphragms on the phase difference structure. With the polarization-type three-dimensional display device and manufacturing method thereof, the vertical viewing angle of the polarization-type three-dimensional display device can be increased while the aperture ratio is guaranteed.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to a passive polarized three-dimensional display device and a manufacturing method thereof. Background technique [0002] like figure 1 As shown, the structure of a passive polarized three-dimensional (3D) display device using a phase difference structure includes: from left to right, a backlight module (BackLightUnit, BLU) 101, a first polarizer (Polarizer, POL) 102, a film A transistor (ThinFilmTransistor,) array substrate 103 , a color filter substrate (ColorFilter, CF) 104 , a second polarizer 105 , and a phase difference structure 106 . Wherein, the space between the array substrate 103 and the color filter substrate 104 is filled with liquid crystal ( figure 1 not shown in ). A plurality of patterned retardation films 107 are arranged on the retardation structure 106 , and a plurality of black matrix strips 108 are arranged on a side of the color filter substrate 104 clo...

AI Technical Summary

Problems solved by technology

[0003] In order to ensure the aperture ratio of each pixel, the width of the black matrix strips 108 cannot be too large, and the thickness of the color filter substrate 104 and the second polarizer 105 is also difficult to make smaller, so it is difficult for a passive polarized three-dimensional display device to have large vertical viewing angle
