Problems solved by technology

However, in the case of a flattening film used as a color filter, there are problems such as a significant decrease in flattening properties and transparency.
In addition, although polyimide or polyamic acid is soluble in solvents such as N-methylpyrrolidone or γ-butyrolactone, it has low solubility in glycol solvents or ester solvents, so it is difficult to apply to flat surfaces. Chemical film production line

Abstract

To provide a material which can be formed into a cured film having high solvent resistance, liquid crystal-aligning properties, high transparency and high planarization, and which can be dissolved in a glycol-type solvent and is therefore applicable in the production line for a planarized film of a color filter when used in the formation of a cured film from the material. Disclosed are: a polyester resin solution for the production of a thermally cured film, which comprises a polyester polymer having a structural unit represented by the formula (1); and a cured film, a liquid crystal alignment layer and a planarized film each of which is produced from the polyester resin solution. (1) wherein A and B independently represent an organic group containing a ring structure.

Description

technical field The present invention relates to a thermosetting film-forming polyester resin solution and a cured film obtained from the thermosetting film-forming polyester resin solution. More specifically, the present invention relates to a polyester resin solution for forming a thermosetting film, the cured film, and uses of the cured film for forming a thermosetting film having high transparency, planarization, and liquid crystal orientation ability . This resin solution for thermosetting film formation is especially suitable for the color filter overcoating agent which has the function of the liquid crystal alignment in a liquid crystal display. Background technique Generally, in optical devices such as liquid crystal display elements, organic EL (electroluminescent) elements, and solid-state imaging elements, a protective film is provided on the surface of the element to prevent exposure to solvents or heat during the manufacturing process. Such a protective film n...
