Description

A composition, a liquid-crystal aligning agent, a liquid-crystal aligning film, and a liquid-crystal display element {COMPOSITION, LIQUID CRYSTAL ALIGNMENT AGENT, LIQUID CRYSTAL ALIGNMENT FILM, AND LIQUID CRYSTAL DISPLAY ELEMENT}

This invention relates to the liquid-crystal aligning agent used in manufacture of the composition used for formation of a resin film, and a liquid crystal display element, the liquid crystal aligning film obtained from this liquid-crystal aligning agent, and the liquid crystal display element using this liquid crystal aligning film.

DESCRIPTION OF RELATED ART The resin film which consists of organic materials, such as a polymeric material, attracts attention, such as the ease of formation, insulating performance, and is widely used as an interlayer insulating film, a protective film, etc. in an electronic device. Especially, in the liquid crystal display element well-known as a display device, the resin film which consists of an organic material or an inorganic material is used as a liquid crystal aligning film.

Currently, a composition containing a polyimide-based polymer excellent in durability and a polysiloxane-based polymer obtained by polycondensing an alkoxysilane is used as a composition for forming a resin film industrially used.

In recent years, the inorganic resin film formed from the composition containing a polysiloxane type polymer is used for an interlayer insulating film and a protective film, Furthermore, a liquid crystal aligning film. Especially, in a liquid crystal display element, the objective (for example, patent document 1) to improve the orientation of the liquid crystal with respect to a heat|fever, raises the film hardness of a liquid crystal aligning film, and improves the print applicability of a liquid-crystal aligning agent The liquid-crystal aligning agent and liquid-crystal aligning film which used a polysiloxane-type polymer are proposed for the purpose of that (for example, patent document 2).

Japanese Patent Laid-Open No. 2001-27761 International Publication No. 2008/044644

The resin film obtained from a polysiloxane-type polymer is widely used for the liquid crystal aligning film of the interlayer insulating film and a protective film in an electronic device, and also a liquid crystal display element, etc. And about these, improving the coating-film property of a resin film, a protective film, and a liquid crystal aligning film is calculated|required. That is, the improvement of the coating-film property of these films becomes effective in order to suppress the defect of the electronic device and liquid crystal display element which generate|occur|produce with a coating-film property defect.

BACKGROUND ART In recent years, liquid crystal display elements have been widely put to practical use in large-screen liquid crystal televisions and high-definition mobile applications (display parts of digital cameras and mobile phones). Concomitantly, the size of the substrate used and the unevenness of the substrate step are increasing compared to the conventional one. Also in such a situation, it is calculated|required by the point of the improvement of the display characteristic of a liquid crystal display element, and suppression of a defect that a liquid crystal aligning film is uniformly coated with respect to a large board|substrate and a level|step difference. In particular, it is calculated|required that a liquid crystal aligning film is coated with a uniform film thickness with respect to the unevenness|corrugation of a board|substrate level difference (it is also said that it improves a level difference followable|trackability).

Since the molecular weight of a polysiloxane-type polymer is low as for the composition obtained from a polysiloxane-type polymer, and a liquid-crystal aligning agent, the level|step difference followable|trackability of a resin film and a liquid crystal aligning film (it is also called a resin film collectively) becomes low. That is, it is not possible to obtain a resin film having a uniform film thickness with respect to the unevenness of the substrate level. Specifically, the resin film is not coated on the convex portion of the substrate step, or the film thickness thereof tends to be thin. With it, it becomes impossible to express the function as an interlayer insulating film and a protective film in an electronic device, and also the liquid crystal aligning film of a liquid crystal display element, and it becomes easy to become these defects.

Moreover, a liquid crystal aligning film is used also in order to control the angle of the liquid crystal with respect to a board|substrate, ie, the pretilt angle of a liquid crystal. In particular, in VA (Vertical Alignment) mode or PSA (Polymer Sustained Alignment) mode, etc., since it is necessary to vertically align the liquid crystal, the liquid crystal aligning film has the ability to vertically align the liquid crystal (also called vertical alignment property or high pretilt angle). do) is required. Moreover, it is becoming important not only high vertical alignment property but the stability to a liquid crystal aligning film. In particular, in a liquid crystal display device using a backlight with a large amount of heat and a large amount of light to obtain high luminance, for example, a car navigation system or a large-sized television, when used or left under an environment exposed to high temperature and light irradiation for a long time there is Under such harsh conditions, when the vertical alignment property is lowered, problems such as that the initial display characteristics are not obtained or that non-uniformity occurs in the display occur.

Then, an object of this invention is to provide the composition which has the said characteristic. That is, an object of the present invention is to provide a composition capable of suppressing the occurrence of pinholes accompanying repelling when forming a resin film, and furthermore, providing a composition with high level difference followability with respect to the unevenness of the stepped substrate.

Moreover, the liquid-crystal aligning agent using the composition of this invention WHEREIN: When forming a liquid crystal aligning film, generation|occurrence|production of the pinhole accompanying repelling can be suppressed, Furthermore, liquid-crystal aligning agent with high step|step difference followable|trackability with respect to the unevenness|corrugation of a step board|substrate. is to provide Moreover, even after being exposed to irradiation of high temperature and light for a long time, it is providing the liquid-crystal aligning agent used as the liquid crystal aligning film which can express a stable pretilt angle.

In addition, it exists in providing the liquid crystal display element which has the resin film obtained from said composition, the liquid crystal aligning film obtained from said liquid-crystal aligning agent, and said liquid crystal aligning film.
