Definitions
- the present invention relates to a thermosetting film-forming composition having photo-alignment properties and a cured film formed therefrom. More specifically, the present invention relates to a thermosetting film-forming composition having high transparency, liquid crystal alignment ability, high solvent resistance and heat resistance in a thermosetting film, and application of the thermosetting film.
- the composition for forming a thermosetting film having photo-alignment property of the present invention is a color filter having a polymerizable liquid crystal alignment function for forming a built-in retardation layer in a patterned retardation plate and a liquid crystal display, particularly used in 3D displays. Suitable for overcoat agent.
- a protective film is provided to prevent the element surface from being exposed to a solvent or heat during the manufacturing process.
- This protective film is required not only to have high adhesion to the substrate to be protected and high solvent resistance, but also to have excellent performance such as heat resistance.
- a protective film is used as a protective film for a color filter used in a color liquid crystal display device or a solid-state imaging device, it is highly transparent to maintain the transmittance of light transmitted through the color filter. It is required that the film has a property.
- phase difference material a phase difference material
- a polymerizable liquid crystal solution is applied and aligned, and then light is applied.
- Cured materials are commonly used.
- the lower layer film needs to be a material having orientation after rubbing treatment or polarized UV irradiation. Therefore, after forming a liquid crystal alignment layer on the overcoat of the color filter, a retardation material is formed (see FIG. 1A). If a film (see FIG. 1B) that also serves as an overcoat of the liquid crystal alignment layer and the color filter can be formed, great advantages such as cost reduction and a reduction in the number of processes can be obtained. A material that can also be used is strongly desired.
- highly transparent acrylic resin is used for the overcoat of the color filter.
- glycol solvents such as propylene glycol monomethyl ether and propylene glycol monomethyl ether acetate
- ester solvents such as ethyl lactate and butyl lactate
- ketone solvents such as cyclohexanone and methyl amyl ketone are easy to handle and apply.
- thermosetting or photocuring acrylic resin is taken (patent documents 1, 2).

- the liquid crystal alignment layer is irradiated with a normal polarized UV exposure (for example, 100 mJ / cm 2 ), the photodimerization reaction rate is low and not sufficiently crosslinked. , Solvent resistance and heat resistance are low. Therefore, when a polymerizable liquid crystal is applied to form a phase difference material layer on the liquid crystal alignment layer, the liquid crystal alignment layer is dissolved and cannot exhibit sufficient alignment. Further, when the exposure dose is increased to 1 J / cm 2 or more in order to increase the photodimerization reaction rate, the orientation of the polymerizable liquid crystal is improved, but the exposure time becomes very long, so this is not a practical method. .
- the material used for the conventional liquid crystal alignment layer was a material having only a photodimerization site as a cross-linking site, the number of cross-linking sites is small as a whole, and the liquid crystal alignment layer produced has sufficient heat resistance. It will not be. For this reason, there is a concern that the liquid crystal alignment layer contracts greatly during the manufacturing process of the display element performed at 200 ° C. or higher after the retardation material is formed.
- a circularly polarized glasses method has been put to practical use as one of 3D display methods.
- a patterned retardation plate is attached on a panel of a liquid crystal display.
- This patterned retardation plate is generally produced by optical patterning a retardation material made of a polymerizable liquid crystal.
- Optical patterning of the polymerizable liquid crystal can be performed by irradiating the photo-alignment film with polarized light having different polarization directions.
- time is required for the polarization exposure process, so that it is necessary to improve the alignment sensitivity of the photo-alignment film in order to improve productivity.
