Description
Technical field
The invention relates to a kind of liquid crystal alignment composition, refer to a kind of liquid crystal alignment composition being applicable to ink jet type printing coating method especially.
Background technology
Liquid-crystal display mainly utilizes extra electric field that Liquid Crystal Molecules Alignment state is changed, and then causes polarisation of light state and direction to change, and uses the display effect obtaining comparison of light and shade.
Along with the expansion of screen sizes, liquid-crystal display has developed in each picture element the liquid crystal display device that membrane transistor (Thin-Film Transistor, TFT) is all housed.When liquid crystal molecule is inserted between a pair substrate containing electrode, because liquid crystal is parallel different from the permitivity in perpendicular molecules direction, therefore need the arrangement mode controlling liquid crystal molecule by controlling electric field.On the other hand, because liquid crystal molecule has birefringent characteristic, the polar biased direction of polar biased light can be regulated and controled by the change of Liquid Crystal Molecules Alignment state.The change of Liquid Crystal Molecules Alignment state must by allowing liquid crystal molecule have the orientation of uniform tilt angle and fixed-direction to reach on substrate.Mode conventional is at present on substrate, be coated with one deck alignment film, the orientation controlling liquid crystal molecule by this alignment film and the tilt angle providing liquid crystal molecule stable.When extra electric field is closed, liquid crystal molecule returns to original arrangement against the high forces (Anchoring force) and coefficient of elasticity thereof with alignment film interface.
The method that current industry prepares alignment film is by liquid crystal alignment composition coating on the surface of the substrate, utilizes friction or other modes that the molecule of this film surface is directed, provides follow-up liquid crystal molecule of inserting to topple over towards fixed-direction by this.This orientation composition can comprise polyvinyl alcohol, polyoxyethylene glycol, polymeric amide, polyamic acid or polyimide, wherein polyamic acid and polyimide have excellent heat-resistant quality and good machinery, electric and endurance owing to having, and are the most often utilized as alignment film material.Polyamic acid carries out by diamines and tetracarboxylic acid or tetracarboxylic dianhydride the polymer that polyreaction obtains, and polyimide is generally undertaken obtained by high temperature dehydration ring-closure reaction [namely imidization (Imidization)] by polyamic acid.
The mainly roll printing printing of past alignment film coating method, is transferred to substrate by alignment film material, to obtain the alignment film of uniform film thickness by APR plate (ASAHI KASEI photosensitive resin plate).But except APR plate need are cleaned and changed, expensive spreading roller (Doctor Roll) and anilox roll (AniloxRoll) also need periodic replacement, and especially run into large size panel, this problem will be more obvious.Therefore, in order to the demand in response to large size panel, the coating of alignment film turns to ink jet type coating method by the coating method of APR plate transfer printing gradually.
But, existing ink jet type printing technology, though there are many advantages being better than roll printing printing, but still have many technology to be overcome, such as, for be coated on substrate and to form the liquid crystal alignment composition of liquid crystal orienting film in ink jet type printing, in coating process, except the precipitation risk that need reduce the alignment film material of polyamic acid or polyimide, also need stable drop-coated to have troubles and high collimation, and this orientation composition also should have excellent diffustivity and levelling property on substrate, diffusion inequality or the unequal situation generation of thickness is produced to avoid formed alignment film.
Summary of the invention
Therefore, object of the present invention, namely one is being provided to be applicable to ink jet type mode of printing, in coating process, except the precipitation risk that can reduce the alignment film material of polyamic acid or polyimide, there is stable drop-coated simultaneously have troubles and high collimation, and the alignment film formed also has excellent diffustivity and the liquid crystal alignment composition of levelling property.
So liquid crystal alignment composition of the present invention, comprise at least one polymkeric substance and mixed solvent.
This polymkeric substance is selected from polyamic acid, polyimide or both combination aforementioned.
This mixed solvent is the combination being selected from butyl glycol ether and nitrogen-sec.-propyl-2-Pyrrolidone, or the combination of butyl glycol ether, nitrogen-sec.-propyl-2-Pyrrolidone and secondary solvent, and wherein, this secondary solvent can increase this mixed solvent to this structure adaptability degree.
Effect of the present invention utilizes this mixed solvent containing butyl glycol ether, nitrogen-sec.-propyl-2-Pyrrolidone, this liquid crystal alignment composition is allowed to be applied in the process of substrate in use ink jet type mode of printing, this polymkeric substance can be reduced and separate out risk, and make this liquid crystal alignment composition in coating process, have stable drop-coated to have troubles and outside high collimation, also there is excellent diffustivity and levelling property on substrate, and formed alignment film can be avoided to produce diffusion inequality or the unequal situation generation of thickness.
