Embodiment 1

[0041] Such as image 3 As shown, a phase difference plate according to an embodiment of the present invention, the phase difference plate 20 includes a plurality of strip-shaped regions of equal width formed on the substrate, the strip-shaped regions are made of liquid crystal photo-alignment materials, and the plurality of strip-shaped regions In the region, the liquid crystal molecules in the liquid crystal photoalignment material are horizontally aligned strip regions and the liquid crystal molecules in the liquid crystal photoalignment material are vertically aligned strip regions are arranged alternately, and the horizontal orientation is parallel to the substrate , the vertical orientation is the direction perpendicular to the substrate. image 3 Among them, A is a vertically oriented strip region, and B is a horizontally oriented strip region.

[0042] Preferably, the above-mentioned substrate is a color filter substrate 10, and in the direction along the staggered ar...

Embodiment 2

[0056] This embodiment is a display device, including the phase difference plate described in Embodiment 1. The display device with the phase difference plate 20 can produce a glasses-like 3D display effect with a strong three-dimensional effect.

Embodiment 3

[0058] Such as Figure 6 and Figure 7 As shown, the present embodiment is the manufacturing method of the retardation plate 20 described in the first embodiment, which includes the following steps:

[0059] S1. Forming a liquid crystal photo-alignment layer on the substrate; specifically, a layer of liquid crystal photo-alignment material can be coated on the substrate by coating or spraying to prepare for the strip-shaped area formed in the next step;

[0060] S2. Exposing the liquid crystal photo-alignment layer twice to form a plurality of striped regions of equal width, so that the alignment of the liquid crystal molecules is horizontally aligned and the alignment of the liquid crystal molecules is vertically aligned. The regions are arranged in a staggered manner; wherein, the horizontal orientation is a direction parallel to the substrate, and the vertical orientation is a direction perpendicular to the substrate.

[0061] Preferably, the above-mentioned substrate is ...

Abstract

A phase difference plate, a manufacturing method thereof and a display device are provided. The phase difference plate includes: a substrate; and a plurality of strip-shaped regions with an equal width, formed on the substrate and made of liquid crystal photoalignment material, wherein strip-shaped regions in which liquid crystal molecules in the liquid crystal photoalignment material are aligned in a horizontal direction and strip-shaped regions in which liquid crystal molecules in the liquid crystal photoalignment material are aligned in a vertical direction are arranged alternately along an arrangement direction, the horizontal direction is a direction parallel with the substrate and the vertical direction is a direction perpendicular to the substrate.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a retardation plate, a display device and a manufacturing method of the retardation plate. Background technique [0002] As we all know, the 2D displays we usually see cannot provide us with depth information like the real world. The key reason why we can distinguish the depth of field (3D effect) is that the two eyes of a person have a position difference caused by a pupillary distance of about 60mm. The two pictures with "binocular parallax" become a pair of "stereoscopic image pair", which, through the fusion of the visual cortex of the human brain, produces a stereoscopic effect. 3D display is divided into naked-eye type and glasses type. The mainstream technologies of glasses type include chromatic aberration type, shutter glass technology and pattern retardation technology. [0003] The polarized glasses-type stereoscopic display belongs to the above-mentioned pattern de...
