Embodiment 1

[0052] Such as Figure 2a As shown in and 2b, the present embodiment has recorded a kind of manufacturing method of retardation plate, comprises the following steps:

[0053] S1: disposing an alignment material 220a on the substrate 210;

[0054]S2: performing an alignment treatment on the alignment material 220a to form an alignment layer 220, as shown in FIGS. 2b(1)-2b(3);

[0055] S3: disposing a layer of RM material 230a on the alignment layer 220, as shown in FIG. 2b (3);

[0056] S4: Form a mask plate 240 on at least one side of the RM material 230a, as shown in FIG. The transmittance of the mask area 242 is smaller than the transmittance of the first mask area 241;

[0057] S5: The RM material 230a is cured by UV exposure for the first time, so that the RM material 230a respectively corresponding to the first mask area 241 and the second mask area 242 is cured to form a first retardation area with different predetermined film thicknesses 231 and the second phase dif...

Embodiment 2

[0072] Such as image 3 As shown, this embodiment describes a phase difference plate obtained by the manufacturing method described in Embodiment 1, including a substrate 310, an alignment layer 320 on the substrate 310, and an RM layer 330 on the alignment layer 320. The RM The layer 330 includes a first phase difference region 331 and a second phase difference region 332 respectively corresponding to the first view and the second view, and the first phase difference region 331 and the second phase difference region 332 have different film thicknesses.

[0073] In this embodiment, the RM layer 330 further includes an RM isotropic cured layer corresponding to the positions of the first phase difference region 331 and the second phase difference region 332 . The RM isotropic solidified layer 333 is formed by curing the RM material above the phase transition temperature (that is, the clearing point), and does not have the performance of liquid crystal and will not form a phase d...

Embodiment 3

[0078] This embodiment describes a display device, a display panel and a phase difference plate located on the light-emitting side of the display panel.

[0079] Wherein, the phase difference plate may be the phase difference plate described in the second embodiment.

[0080] In this embodiment, the display device further includes a polarizer forming a combined structure with the phase difference plate,

[0081] The polarizer includes a first cellulose triacetate film, a polyvinyl alcohol film and a second cellulose triacetate film distributed in layers in sequence;

[0082] The phase difference plate uses the first cellulose triacetate film or the second cellulose triacetate film as a substrate, and the first cellulose triacetate film or the second cellulose triacetate film The alignment layer and the thermotropic liquid crystal layer are sequentially formed on either side.

[0083] In this embodiment, a protective film is provided on both sides of the combined structure. ...

Abstract

The invention discloses a phase difference board and a manufacture method and a display device of the phase difference board. The manufacture method comprises the steps of arranging alignment materials on a base board and performing alignment processing to form an alignment layer; arranging a layer of reference material (RM) material on the alignment layer; forming a covering film board on at least one side of the RM material, wherein a coving film is provided with a first covering film area and a second covering film area, and transmittance of the second covering film area is smaller than that of the first covering film area; performing a first-time ultraviolet (UV) exposure solidification on the RM material to enable the RM material corresponding to the first covering film area and the second covering film area respectively to solidify to form a first phase difference area and a second phase difference area having different preset film thickness; heating the RM material to a temperature above a phase transformation temperature of the RM material, and then performing a second-time solidification on the RM material which is not fully solidified; or adopting solution to remove the RM material which is not fully solidified; and removing the covering film board. The manufacture method of the phase difference board is few in process program and low in cost.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a phase difference plate, a manufacturing method thereof, and a display device. Background technique [0002] Stereoscopic display has become a major trend in the display field. The fundamental principle of stereoscopic display is that parallax produces stereo, even if people's left eye sees the left eye picture, and the right eye sees the right eye picture. The left and right eyes view the picture as a pair of stereoscopic image pairs with parallax. [0003] One method to achieve stereoscopic display is serial display, that is, at the first moment, the monitor displays the image for the left eye, and only the left eye of the viewer can see the display image; at the second moment, the display displays the image for the right eye, and only the viewer The right eye of the viewer sees the display picture, and the persistence of the image on the retina of the human eye is used to ...
