Description

Anti-dazzle property optical stacking body

Background of invention

Related application

The application serves as the right of priority that Paris Convention is advocated on the basis with Japanese patent application 2005-44231 number and Japanese patent application 2005-95919 number.Therefore, the application comprises whole application contents of these patented claims.

Technical field

The present invention relates to be used for the anti-dazzle property optical stacking body of displays such as CRT, liquid crystal panel.

Background technology

In the such image display device of cathode tube display device (CRT), plasma display (PDP), electroluminescent display (ELD) or LCD (LCD), requiring to prevent to be appeared before one's eyes by external light reflection or image, the contrast that causes descends, the visual reduction.Therefore, in order to alleviate appearing before one's eyes or reducing reflectivity of image, generally use light scattering principle or principle of optical interference, at the most surperficial antireflective layered material that is provided with of image display device.

Known at existing image display device for example in the LCD, show in order to adjust the image that optical characteristics realizes high-quality, use anti-dazzle property duplexer as one of antireflective layered material.Anti-dazzle property duplexer is to be reduced and used by the appear before one's eyes visuality that causes of external light reflection or image in order to prevent in the image display device.Anti-dazzle property duplexer is to realize by form the antiglare layer with concaveconvex shape on general base material.Known at existing image display device for example in the LCD, show in order to adjust the image that optical characteristics realizes high-quality, use anti-dazzle property duplexer as one of antireflective layered material.Anti-dazzle property duplexer is to be reduced and used by the appear before one's eyes visuality that causes of external light reflection or image in order to prevent in the image display device.Anti-dazzle property duplexer is that the composition that will add various particles is solidified into concaveconvex shape, or handles the formation concaveconvex shape by implementing the embossing excipient, thereby (the open 2004-341070 of Jap.P.) that adjust.

In recent years, along with the requirement that becomes more meticulous of the height of panel resolution, the concaveconvex shape of antiglare layer becomes more and more finer.Therefore, adopt the anti-dazzle property duplexer of this formation, become more meticulous, can't adopt if the concaveconvex shape of the roomy curve of formation then is unsuitable for height.On the other hand, the height of following panel resolution becomes more meticulous and the miniaturization of the concaveconvex shape that forms, though can tackle the requirement that becomes more meticulous of the height of panel resolution, often be pointed out that external light has picture display face to look to turn white degradation problem under (albefaction), the contrast at the reflected light on the display surface.In addition, when anti-dazzle property duplexer like this is used for image display surface such as notebook computer, though can bring into play sufficient optical characteristics to a certain extent, but transmitted light from the backlight back side of display interior, when seeing through concavo-convex that is formed at the most surperficial anti-dazzle property duplexer of panel, these concaveconvex shapes play fine lens, occur disorderly states " flicker " such as shown pixel easily, make anti-dazzle property duplexer be difficult to bring into play self effect sometimes.Especially the height along with panel resolution becomes more meticulous, and occurs this " flicker " easily, must effectively prevent this situation.

As eliminate should " flicker " method, be purpose to improve vividness, adopted by making the concave-convex surface densification and adding and the resin of formation antiglare layer has the scattering particle of refringence to come anti-dazzle property duplexer is given the method for scattering-in effect etc.Yet,, make the visual reduction of general image sometimes though arbitrary method has all solved the problem of " flicker " well.In anti-dazzle property duplexer, prevent the become more meticulous method of panel flash of height, be regarded as the albefaction on surface or the gonorrhoea that causes of scattering-in effect etc. and make contrast main reasons for decrease, " preventing flicker " and " raising contrast " have balance to concern, thereby be difficult to satisfy both.For example, the black repeatability that comprises gorgeous black sense (black with glossy gloss) during picture shows, contrast etc. are wanting in.That is, the gray shade scale of the black in the bright chamber shows that particularly under low gray shade scale, the tonal difference of black is difficult to differentiate sometimes, and sensitivity is low.Specifically, when differentiating black and grey, the black of same tone is blured, can only be told to color sometimes.Especially, we can say the anti-dazzle property duplexer that has anti-scintillation properties, its visuality is obviously low.

Therefore at present, expectation is developed the flicker that can effectively prevent imaging surface and can be realized the particularly optical laminate of gorgeous black sense of black repeatability, especially, not only on LCD (LCD), at cathode tube display device (CRT), plasma display (PDP), fluorescent display tube, also operable optical laminate has been subjected to fervent expectation on other purposes such as field emission escope.
