Disclosed is a temperature-controlled alignment device based on multi-model glass technology. The device includes a stage divided into at least two areas and heating modules corresponding to respective areas. Each of the heating modules includes a heat conductive sheet, a liquid pipe, and an electric heater. Different areas are heated by arranging a heating module for each of the areas, so that reaction rates of reactive monomers in panels of different areas have a same reaction rate so as to form a same pretilt angle.

A liquid crystal composition includes at least one of a monofunctional compound represented by Formula (1) defined herein and a monofunctional compound represented by Formula (2) defined herein, and at least one of a difunctional compound represented by Formula (3) defined herein and a multifunctional compound represented by Formula (4) defined herein.

A liquid crystal display device having a liquid crystal composition, requiring neither an alignment film nor alignment treatment on a substrate. The problem is solved by a low molecular weight polar compound for homogeneously aligning a liquid crystal medium relative to the substrate, for example, the low molecular weight polar compound represented by formula (1).

Formula 95

M-P(1)

In formula (1), M is a nonpolar group having 1 or more carbons, and P is a polar group.

The spontaneous orientation aid for a liquid crystal composition provides storage stability and allows liquid crystal molecules to be vertically aligned without a PI layer when added to a liquid crystal composition. The spontaneous orientation aid for a liquid crystal composition includes a compound having a partial structure represented by formula (i), particularly in which K.sup.i1 is represented by one of formula (K-1) to formula (K-11). When used in a liquid crystal composition, the spontaneous orientation aid can adsorb to substrates sandwiching a liquid crystal composition (liquid crystal layer) and keep the liquid crystal molecules aligned in a vertical direction. The spontaneous orientation aid makes it possible to align liquid crystal molecules without a PI layer (to induce vertical alignment of liquid crystal molecules under no applied voltage and to achieve horizontal alignment of the liquid crystal molecules under an applied voltage).

The present application provides a ligand-modified quantum dot material, a method of fabricating a liquid crystal display panel, and a liquid crystal display panel. The ligand-modified quantum dot material of the present application can occur a polymerization with the ligand-modified quantum dot material under ultraviolet irradiation to form a polymer, while the polymer deposits on a substrate to form a polymer film, which can replace the PI alignment film, so that an alignment process of liquid crystal is simplified, and a cost is economized; simultaneously, display quality of a liquid crystal display panel can be improved by the quantum dots anchored in the polymer film. The method of fabricating the liquid crystal display panel of the present application eliminates the fabricating process of the PI alignment film, the method has simple process and low cost, and a liquid crystal display panel obtained thereby has better display quality. The liquid crystal display panel of the present application utilizes the polymer film, which is obtained by polymerizing the ligand-modified quantum dot material and a polymerizable monomer, to replace the PI alignment film, so as to greatly enhance quality of the panel, and to have a low fabricating cost.
