Definitions
- the present invention relates to a cured film forming composition that can be used as a liquid crystal aligning agent for photo-alignment for aligning liquid crystal molecules, an alignment material, and a retardation material.
- the present invention is useful for producing a patterned retardation material used in a circularly polarized glasses type 3D display and a retardation material used in a circularly polarizing plate used as an antireflection film of an organic EL display.
- the present invention relates to a cured film forming composition, an alignment material, and a retardation material that can be used as a liquid crystal alignment agent for photo-alignment.
- a retardation material is usually disposed on a display element such as a liquid crystal panel.
- a retardation material a plurality of two kinds of retardation regions having different retardation characteristics are regularly arranged, and a patterned retardation material is formed.
- a retardation material patterned so as to arrange a plurality of retardation regions having different retardation characteristics is referred to as a patterned retardation material.
- the patterned retardation material can be produced, for example, by optically patterning a retardation material made of a polymerizable liquid crystal as disclosed in Patent Document 1.
- Optical patterning of a retardation material made of a polymerizable liquid crystal utilizes a photo-alignment technique known for forming an alignment material for a liquid crystal panel. That is, a coating film made of a photo-alignment material is provided on a substrate, and two types of polarized light having different polarization directions are irradiated on the coating film. Then, a photo-alignment film is obtained as an alignment material in which two types of liquid crystal alignment regions having different liquid crystal alignment control directions are formed.
- a solution-like retardation material containing a polymerizable liquid crystal is applied on the photo-alignment film to realize the alignment of the polymerizable liquid crystal. Thereafter, the aligned polymerizable liquid crystal is cured to form a patterned retardation material.
- the anti-reflective film of the organic EL display is composed of a linear polarizing plate and a quarter-wave retardation plate, converts external light directed to the panel surface of the image display panel into linear polarized light by the linear polarizing plate, and continues to the quarter wavelength. It is converted into circularly polarized light by the phase difference plate.
- the extraneous light by the circularly polarized light is reflected by the surface of the image display panel or the like, but the rotation direction of the polarization plane is reversed during the reflection.
- this reflected light is converted from the quarter-wave retardation plate into linearly polarized light in the direction shielded by the linear polarizing plate, and then shielded by the subsequent linear polarizing plate, As a result, the emission to the outside is remarkably suppressed.
- Patent Document 2 discloses that this optical film has a reverse dispersion characteristic by configuring a 1/4 wavelength phase difference plate by combining a 1/2 wavelength plate and a 1/4 wavelength plate. Has been proposed. In the case of this method, an optical film can be formed with reverse dispersion characteristics using a liquid crystal material with positive dispersion characteristics in a wide wavelength band used for displaying a color image.
- Patent Documents 3 and 4 As liquid crystal materials applicable to the retardation layer, those having reverse dispersion characteristics have been proposed (Patent Documents 3 and 4). According to the liquid crystal material having such a reverse dispersion characteristic, instead of forming a quarter-wave retardation plate by combining two half-wave plates and a quarter-wave plate to form a quarter-wave retardation plate. It is possible to achieve an optical film capable of ensuring a desired phase difference in a wide wavelength band with a simple configuration.
- An alignment layer is used to align the liquid crystal.
- a method for forming the alignment layer for example, a rubbing method or a photo-alignment method is known.
- the photo-alignment method does not generate static electricity or dust, which is a problem of the rubbing method, and can control the alignment process quantitatively. It is useful in.
- acrylic resins and polyimide resins having photodimerization sites such as cinnamoyl groups and chalcone groups in the side chain are known as usable photo-alignment materials. These resins have been reported to exhibit the ability to control the alignment of liquid crystals (hereinafter also referred to as liquid crystal alignment) when irradiated with polarized UV light (see Patent Documents 5 to 7).
- the alignment layer is required to have solvent resistance in addition to the liquid crystal alignment ability.
- the alignment layer may be exposed to heat or a solvent in the manufacturing process of the retardation material. When the alignment layer is exposed to a solvent, the liquid crystal alignment ability may be significantly reduced.
- Patent Document 8 in order to obtain stable liquid crystal alignment ability, a liquid crystal aligning agent containing a polymer component having a structure capable of crosslinking reaction by light and a structure crosslinked by heat, and light.
- a liquid crystal aligning agent containing a polymer component having a structure capable of crosslinking reaction and a compound having a structure crosslinked by heat has been proposed.

- an acrylic resin having a photodimerization site such as a cinnamoyl group or a chalcone group in a side chain cannot obtain sufficient characteristics when applied to the formation of a retardation material. It was issued.
- a large amount of polarized UV exposure is required.
- the polarized UV exposure amount is much larger than the polarized UV exposure amount (for example, about 30 mJ / cm 2 ) sufficient to align the liquid crystal for a normal liquid crystal panel.
- the reason for increasing the amount of polarized UV exposure is that, in the case of retardation material formation, unlike liquid crystals for liquid crystal panels, polymerizable liquid crystals are used in the state of solution and applied onto the alignment material. Yes.
