Problems solved by technology

However, if the distance between the dam-like protrusions or the distance between the slits is very wide, the propagation of the inclination of the liquid crystal molecules will take a long time, and when the necessary voltage for display is applied to the liquid crystal layer, the liquid crystal molecules will response becomes very slow

The array substrate 10 has a support substrate 11 including an insulating transparent substrate made of glass or the like, various wirings formed on the transparent substrate, pixel electrodes, TFTs, and the like. The color filter substrate 20 has an insulating transparent substrate made of glass or the like, and a support substrate 21 including a color filter, a black matrix, a common electrode, and the like formed on the transparent su...

Embodiment 1

[0105] Hereinafter, Example 1 in which the liquid crystal cell included in the liquid crystal display device of Embodiment 1 is actually produced is shown. First, prepare a pair of supporting substrates, and coat the surfaces of the pair of substrates respectively, as a material for vertical alignment film, polyamic acid or polyimide solution with photoreactive functional groups in the side chain, at 80°C Prebake at 200°C for 60 minutes.

[0106] Next, from a direction inclined at 45° relative to the surface of the supporting substrate, a 100mJ / cm 2 Irradiation of ultraviolet polarized light having a wavelength near 300 nm was performed to perform photo-alignment treatment.

[0107] Next, a sealant is applied to one support substrate, beads are scattered on the other support substrate, the pair of substrates are attached to each other, and a liquid crystal layer containing a liquid crystal material having a negative dielectric constant anisotropy is injected between the pair ...

Embodiment 2

[0122] Example 2 in which the liquid crystal cell included in the liquid crystal display device of Embodiment 1 was actually produced is shown below. In Example 2, except for the polymerizable monomer M T (Monomer for improving pretilt image sticking) and polymerizable monomer M D Each sample was prepared by the same method as in Example 1 except that the material of (the monomer for improving DC image sticking) was different. The polymerizable monomer M of Example 2 T is a compound represented by the following general formula (13), the polymerizable monomer M D It is a compound represented by the following general formula (14).

[0123]

[0124]

[0125] As each sample of Example 2, a polymerizable monomer M was prepared. T The weight ratio and polymerizable monomer M D weight ratio (M T : M D ) is a 9:1 sample (sample B2), a 3:1 sample (sample C2), a 1:1 sample (sample D2), a 1:3 sample (sample E2). In addition, as a reference unit for comparison with the sampl...
