Abstract

A liquid crystal display device being resistant to display unevenness without loss of responsivity and being capable of securing configurational stability is provided. A liquid crystal display device includes: a liquid crystal layer including liquid crystal molecules and a polymer compound including a structure represented by Chemical Formula 1; and a pair of substrates facing each other with the liquid crystal layer in between, where m and n each are an integer of 1 to 4 both inclusive.

Claims (24)

1. A liquid crystal display device comprising:

a liquid crystal layer including liquid crystal molecules and a polymer compound including a structure represented by Chemical Formula 1; and

a pair of substrates facing each other with the liquid crystal layer in between,

where m and n each are an integer of 1 to 4 both inclusive.

2. The liquid crystal display device according to claim 1 , wherein

the polymer compound is present in proximity to at least one of the pair of substrates.

3. The liquid crystal display device according to claim 1 , wherein

an alignment film is provided between each of the pair of substrates and the liquid crystal layer, and

the polymer compound is fixed to the alignment films.

4. The liquid crystal display device according to claim 1 , wherein

m and n in Chemical Formula 1 each are 3 or less.

5. The liquid crystal display device according to claim 1 , wherein

the polymer compound further includes a structure represented by Chemical Formula 2,

6. The liquid crystal display device according to claim 1 , wherein

one of the pair of substrates includes a pixel electrode, and the other includes a common electrode, and

the liquid crystal layer has a negative dielectric constant anisotropy, and includes liquid crystal molecules with pretilt angles of greater than 88° and smaller than 90° with respect to surfaces of the pair of substrates.

7. The liquid crystal display device according to claim 6 , wherein

the common electrode includes an aperture or a notch.

8. The liquid crystal display device according to claim 6 , wherein

the pixel electrode includes a plurality of slits at intervals.

9. The liquid crystal display device according to claim 1 , wherein

one of the pair of substrates includes a pixel electrode and a common electrode,

the liquid crystal molecules have a positive dielectric constant anisotropy, and

the pixel electrode and the common electrode generate a transverse electrical field including a component parallel to surfaces of the pair of substrates.
