Embodiment Construction
[0036] The traditional preparation process of a polymer liquid crystal layer with a specific orientation direction is as follows:
[0037] Such as figure 1 As shown, it is first necessary to prepare the corresponding alignment layer on the substrate: PI material coating → pre-baking → main baking → rubbing (Rubbing) alignment (or UV light alignment → post-baking); and then polymerize the liquid crystal layer Preparation: PLC material coating → pre-baking → UV light polymerization → post-baking.
[0038] It can be seen that the traditional preparation process of a polymer liquid crystal layer with a specific orientation direction is relatively complicated, requiring multiple steps for preparing an alignment layer and multiple steps for preparing a liquid crystal polymer layer, and the preparation efficiency is low.
[0039] Based on this, the embodiments of the present invention provide a composite liquid crystal layer, a preparation method thereof, a display panel and a displ...

Abstract
The invention discloses a composite liquid crystal layer, a preparation method thereof, a display panel and a display device. A process of separately preparing an alignment layer is omitted, and a material with self-assembly characteristics containing a photosensitive group is added to a liquid crystal polymer material to form a polymer liquid crystal composite system. A substrate is directly coated with the polymer liquid crystal composite system. Photo-alignment is firstly carried out on the polymer liquid crystal composite system to make the material with the self-assembly characteristics containing the photosensitive group form a directional alignment structure. The alignment is carried out on the liquid crystal polymer material under the action of the directional alignment structure,and then the aligned liquid crystal polymer material is cured to form a polymer crystal layer with a specific alignment structure. The polymer crystal layer capable of photo-aligning can be formed byphoto-alignment and curing treatment after coating once, which simplifies a process flow and greatly improves the production efficiency.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a composite liquid crystal layer, a preparation method thereof, a display panel and a display device. Background technique [0002] Currently, a polymer liquid crystal layer with a specific orientation direction is used as a compensation layer in a display panel to compensate for the light leakage phenomenon in the display panel. The traditional preparation process of the polymer liquid crystal layer with a specific orientation direction is relatively complicated, and the preparation of the alignment layer and the preparation of the liquid crystal polymer layer need to be carried out separately. Contents of the invention [0003] In view of this, the embodiments of the present invention provide a composite liquid crystal layer, a preparation method thereof, a display panel and a display device, so as to solve the problem of complex preparation process of the existing polymer l...
