Embodiment Construction

[0049] reactive mesogenic compounds

[0050] The reactive mesogenic compound is a compound including a thiophene group and represented by Chemical Formula 1-1.

[0051]

[0052]

[0053] In chemical formula 1-1, A 1 and A 2 express independently or a single bond, "n" and "m" each independently represent an integer ranging from 0 to about 3. Here, "m" and "n" do not represent 0 at the same time. In chemical formula 1-1, A 1 、A 2 and 2,5-thienylene can determine the skeleton of reactive mesogenic compounds.

[0054] B 1 and B 2 Each independently represents a single bond or -(CH 2 ) k -. Here, "k" represents an integer ranging from 0 to about 6. B 1 and B 2 At least one of each -(CH 2 )- can be replaced by -O-, -COO-, -OCO- or -CO-.

[0055] In chemical formula 1-1, D 1 and D 2 Each is a photofunctional group in the reactive mesogen compound that is substantially (substantialliy) activated by light. The photofunctional group is activated by light to ...

Abstract

A reactive mesogen compound, a liquid crystal composition including the reactive mesogen compound, a method of manufacturing a display panel, and a display panel are disclosed. The reactive mesogen compound is represented by Chemical Formula 1-1. In Chemical Formula 1-1, each of A1 and A2 independently represents or a single bond, each of "n" and "m" independently represents an integer in a range of 0 to about 3 ("m" and "n" do not simultaneously represent 0), each of B1 and B2 independently represents a single bond or -(CH2)k- ("k" represents an integer in a range of 0 to 6), at least one -(CH2)- in each of B1 and B2 is replaceable with -O-, -COO-, -OCO- or -CO-, each of D1 and D2 independently represents methacrylate or acrylate, and at least one hydrogen atom of each of A1, A2 and 2,5-thiophene is replaceable with F, Cl, OCH3 or an alkyl group having 1 to about 6 carbon atoms.

Description

technical field [0001] Disclosed herein are a reactive mesogen compound, a liquid crystal composition including the reactive mesogen compound, a method of manufacturing a display panel, and a display panel. More particularly, the present disclosure relates to a reactive mesogen compound that reacts with light, a liquid crystal composition including the reactive mesogen compound, a method of manufacturing a display panel, and a display panel. Background technique [0002] Generally, a liquid crystal display ("LCD") panel includes a first display substrate including switching elements for driving individual pixels, a second display substrate facing the first display substrate, and a display substrate between the first and second display substrates. liquid crystal ("LC") layer between them. A voltage is applied to the LC layer to control light transmittance, allowing the LCD panel to display images. [0003] Super vertical alignment (super vertical alignment, "SVA") mode is a...
