The Ro in-plane retardation of the optical film is 0-2nm, the Rth out-of-plane retardation approaches 0nm, therefore, the invention can be used to replace traditional cellulose triacetate cta protective film of polarization plate, to resolve the problems of liquid crystal display under large angle as reduced black-white contrast and color change.
Description
Technical field
The present invention relates to ultra-low slow-moving blooming and the application of this blooming in polarizing plate protective film.
Background technology
LCD (LCDs) has been widely used on individual computer monitor, digital camera and mobile phone and the large-sized TV.In the LCD panel, Polarizer (Polarizer) is one of fundamental parts of LCD.Polarizer is the tabula rasa that the light of a kind of a certain direction of permission sees through, in the process of making liquid crystal board, must each use a slice up and down, and become alternate directions to insert, main application produces the state that phasic difference presents light and shade for make light source when electric field is arranged with no electric field, to show captions or pattern.Along with the increase of LCD consumption, the Polarizer demand grows with each passing day.The polarization system of light polarizing film is by due to each anisotropy absorber of the light that directive property is arranged in the transparent polymer film, for example the polaroid of polyvinyl alcohol (PVA) (PVA) is after being adsorbed on iodine or a kind of two look dyestuffs in the polyvinyl alcohol film, makes the directive property of its tool single shaft by extension.Expansion along with LCD product usable range; requirement to the damp and hot condition of work of polarisation product is more and more harsher; the polaroid of doing with these materials runs into the problem of dimensional contraction easily in damp and hot reliability testing; the reason of optical characteristics deterioration is because the molecular structure of iodine is easy to destroyed event under hot and humid condition; so light polarizing film needs two surface protective films as supporting and protection; with permanance and the physical strength that keeps it, normally used diaphragm is Triafol T (TAC).These diaphragms need high transmittance, low-birefringence, outstanding heat, cold, light, moisture resistibility and optic homogeneity, that is to say, must no foreign object or the flaw of visual speckle.And with the Triafol T diaphragm of solvent method coating because of its penetrability, outward appearance is good and easy and light polarizing film is pasted so use so far.
Because the TV of large-scale LCD is popularized gradually, has required the TAC diaphragm to have lower birefringence.The Ro value (light hysteresis (in-plane-retardation) in the plane) of TAC is little at present, but Rth value (light hysteresis outside the plane (out-of-plane retardation)) is still big.This Rth value will cause that faulty optical compensation effect is arranged on the LCDs (for example has the contrast decline of black and white and color change (color shift) problem to take place under the wide-angle.Therefore the Rth value need heal better little, particularly on the LCD of IPS (plane internal conversion (in-plane switching)) pattern.Usually, polymkeric substance has its birefringence, and its value raises along with the strand directionality in the polymkeric substance and increases, and Rth value is to be difficult to reduce, and (in-plane) arranges event on the isoplanar because of the strand of polymkeric substance easily tends to.Therefore, in order to reduce birefringence, the method for general using compensation, for example Japan has researched and developed the polymkeric substance (WO2006098517 of zero birefraction (zero-birefringence) recently; JP2006096793), it compensates the positive birefringence of polymkeric substance by using negative birefringence inorganics crystal or adjuvant, to modulate the polymeric blends of zero birefraction.Cyclic olefin polymer (Cyclo the OlefinPolymer) (JP2006124628 that the performance low-birefringence is also arranged; US2004099973; JP2004168063), but its chemical framework is hydrophobic backbone and side chain, if be used for the PVA polarizing plate protective film, they almost are difficult to attached on the hydrophilic PVA.
Summary of the invention
Fundamental purpose of the present invention just provides a kind of ultra-low slow-moving blooming, to improve the optical compensation effect of LCD under wide-angle.
In order to reach above-mentioned and other purpose, ultra-low slow-moving blooming of the present invention mainly comprises: light-transmissive resin, and it has three-dimensional cross-linked structure; And, be scattered in the nanosize metal oxide particle in this light-transmissive resin; Wherein, light hysteresis (Ro in the plane of this blooming; In-plane retardation) between 0～2nm, light sluggishness (Rth outside the plane; Out-of-plane retardation) value is near 0nm.
The present invention also provides Polarizer, mainly comprises polaroid and above-mentioned ultra-low slow-moving blooming, and this blooming is arranged at least one surface of polaroid, with as polarizing plate protective film.
