Definitions
- the present invention relates to a liquid crystal alignment film capable of achieving both panel production cost and film formation quality.
- liquid crystal alignment film As the liquid crystal alignment film, a so-called polyimide-based liquid crystal alignment film, which is obtained by applying and baking a liquid crystal alignment agent mainly composed of a polyimide precursor such as polyamic acid (also called polyamic acid) or a soluble polyimide solution, is widely used.
- a polyimide precursor such as polyamic acid (also called polyamic acid) or a soluble polyimide solution
- liquid crystal aligning agent having a high solid content is required in order to reduce the amount of liquid crystal aligning agent used and increase the production efficiency.
- liquid crystal aligning agent that can achieve a stable film thickness even on a high definition substrate having a large level difference.
- the above technical directions all press the storage stability of the varnish and increase the risk of causing liquid precipitation.
- higher substrate and film adhesion is required due to higher definition of the substrate and slimming of the panel.
- An object of the present invention is to provide a liquid crystal aligning agent that has high adhesion, does not cause precipitation even at a high solid content concentration, and can obtain a stable film thickness, and a liquid crystal alignment film using the same.
- the present invention contains the following component (A), component (B), component (C) and component (D), and the component (C) is 20 to 50% by mass with respect to the total mass of the liquid crystal aligning agent. It is in the liquid crystal aligning agent to contain.
- liquid crystal aligning agent that has high substrate adhesion, does not cause precipitation even at a high solid content concentration, and can obtain a stable film thickness, and a liquid crystal alignment film using the same.
- the liquid crystal aligning agent of this invention is especially effective for application
- the component (A) contained in the liquid crystal aligning agent of the present invention is at least one polymer selected from the group consisting of a polyimide precursor and a polyimide that is an imidized product thereof.
- the polyimide precursor can be represented by the following formula (1).
- X 1 is a tetravalent organic group derived from a tetracarboxylic acid derivative
- Y 1 is a divalent organic group derived from a diamine
- R 1 is a hydrogen atom or a carbon number of 1 to 5 Represents an alkyl group.

下記実施例4~11、比較例4~6について、インクジェット塗布装置(石井表記社製)を用いて、Crを蒸着したガラス基板上に、成膜後の膜厚が100nmになるように、塗布速度250mm/sec、ディスペンス量70pL、塗布面積36×36mmで行った。塗膜の膜厚は、110℃のホットプレート上で1分仮乾燥を行った後、230℃15分の条件で、IRオーブンで焼成した。この際、全ての実施例及び比較例で、面内にムラのない状態で塗布ができることを確認した。この条件下において、本焼成後の膜厚が100nmになる条件で塗布した際の、滴下ピッチを比較した。この際、広い滴下ピッチになるものは、単位距離あたりの滴下液量が少ないことになる。滴下ピッチが長いものは「良好」、滴下ピッチが短いものを「不良」とした。
