Passive polarizing type three-dimensional display device and manufacturing method thereof

Abstract

The embodiment of the invention provides a passive polarizing type three-dimensional display device and a manufacturing method thereof. One side, facing a first polarizing sheet, of an array substrate is provided with shielding strips, one side, facing the array substrate, of a color film substrate is provided with a plurality of black matrix strips, and the orthographic projection of the shielding strips and the black matrix strips covers the boundary line of each pattern phase differential membrane in a phase difference structure. The passive polarizing type three-dimensional display device has the advantage that by utilizing the shielding function of the shielding strips and the black matrix strips, while the opening rate is ensured, the visual angle without optical inference between the adjacent pixels is increased, and the vertical visual angle of the passive polarizing type three-dimensional display device is further increased.

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] Such as 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 (Back Light Unit, BLU) 101, a first polarizer (Polarizer, POL) 102 , a thin film transistor (Thin Film Transistor,) array substrate 103 , a color filter substrate (Color Filter, 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 subst...

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
