Abstract
The present invention provides a light diffuser with excellent surface luminance property, high brightness, uneven luminance surface brightness and excellent tone capable of being used for bottom lighting backlight liquid crystal device light diffuser etc., in particular a light diffuser used for bottom lighting backlight light diffuser for large-scale liquid crystal device or large-scale liquid crystal TV. The present invention provides a light diffuser formed by laminating a functional film on single surface or two surfaces of the thermoplastic resin plate with a bonding layer, which is characterized in relation of thickness of the bonding layer (x1(<mu>m)) and surface roughness concentration (ten percent average roughness concentration Rzl(<mu>m)) of any one surface of the thermoplastic resin plate or the functional film contacting with the bonding layer satisfies formula (i) x1<0.3Rz1(i).
Description
Technical field
The thermoplastic resin system of the present invention relates to complex light diffuser plate.In more detail, relate to the face photism of excellence and briliancy height, tone thermoplastic resin excellent system complex light diffuser plate that the light-emitting area unevenness of brightness is few with diffuser plate of can be used for liquid crystal display etc.
Background technology
Aromatic polycarbonate resin, its mechanical property, thermotolerance, against weather excellence, and be applied to multiple use as the resin with high light line transmitance.For example, in building fields such as dome (sky dome), skylight (top light), arcade (arcade), mansion skirtboard, road side wallboard, a large amount of uses are arranged also.
In these purposes, majority uses as the white light diffuser plate.In the prior art, as the manufacture method of polycarbonate resin white light diffuser plate, proposed in polycarbonate resin, to add the method (referring to patent documentation 1) of light diffusing agents such as mixed calcium carbonate and titanium dioxide, in polycarbonate resin, added the method (referring to patent documentation 2) of the crosslinked polymer particles of mixing portion, in polycarbonate resin, added the method (referring to patent documentation 3) of mixing insoluble acrylic polymers particulate, titanium dioxide and silicon compound.
Light diffusing sheet, as other purposes, the edge light mode or Staight downward type backlight mode surface light source unit or the scanner surface light source unit etc. that can be used for LCD and LCD TV, but the light diffusing sheet of record in the above-mentioned patent documentation 1～3 is when using as above-mentioned surface light source unit, light penetration is low, optical loss is big, therefore, the briliancy reduction is arranged and can not obtain the luminiferous problem of sufficient face.
In recent years, in edge light mode or Staight downward type backlight mode LCD and the liquid crystal display television by using light diffusing sheet purposes, picture advances to maximizing and high polycarbonate system light diffusing sheet and the acrylic acid/styrene resin system light diffusing sheet of dimensional stability competed.Known particularly polycarbonate system light diffusing sheet (resistance to impact, thermotolerance and anti-flammability) aspect quality has excellent performance.
From the unevenness of brightness aspect consideration that improves the liquid crystal panel briliancy and reduce picture integral body, in large-scale LCD and the LCD TV, beyond light diffusing sheet, use diffusion barrier, lens coating, briliancy to improve functional membranes such as film mostly.But, in order to reduce cost and to simplify assembling procedure, even wish to develop functional membrane quantity and reduce the light diffusing sheet that its briliancy and diffusion also do not reduce strongly.
As the poly carbonate resin composition that the edge illumination mode surface light source unit of LCD uses, known have in polycarbonate resin, add the resin combination (referring to patent documentation 4) of lime carbonate or crosslinked polyacrylate resin, in polycarbonate resin, cooperate the resin combination (referring to patent documentation 5) of the crosslinked acryl resin of pearl, in polycarbonate resin, add the crosslinked acryl resin of pearl and the resin combination (referring to patent documentation 6) of fluorescer.Further, the LCD backlight of convex of the trickle section indentation of at least one surface of the light diffusing plate that contains pearl crosslinked acrylic resin formation is disclosed with light diffusing sheet (referring to patent documentation 7).
But, in these poly carbonate resin compositions, also cause optical loss to become big owing to adding a large amount of adjuvants such as light diffusing agent, therefore, be used for LCD Staight downward type backlight or scanner etc., the problem that briliancy is improved is arranged.
In addition, light diffusing sheet, mounting diffusion barrier or lens coating etc. and use as required usually are in patent documentation 8, proposed a kind of complex diffuser, it is the complex diffuser that its pressurization is formed one by the resin that the roller clamping multilayer with prism shape is extruded.
But this light diffusing sheet briliancy performance is insufficient, particularly when using with light diffusing sheet with Staight downward type backlight as large-scale LCD described later, has the more significant problem of its influence.

Summary of the invention
The object of the invention is to provide the light diffusing sheet of a kind of face photism with the excellence that can be used for Staight downward type backlight mode LCD light diffusing sheet etc. and briliancy height, tone excellence that the light-emitting area unevenness of brightness is few, the light diffusing sheet that particularly provides a kind of Staight downward type backlight mode light diffusing sheet that can be used as large-scale LCD or large-scale LCD TV to use.
The inventor for realize above-mentioned problem concentrate one's attention on research found that, in the Staight downward type backlight mode, though in the prior art in order to improve briliancy at the upper surface of light diffusing sheet and to reduce unevenness of brightness and be provided with many from the teeth outwards and have diffusible film and use, but, remain on surfaceness in the particular range by any one the surface that makes the thermoplastic resin board that contacts with tack coat or functional membrane with respect to tack coat, promptly can obtain to demonstrate tone excellence and briliancy height with comparalive ease, the complex diffuser of the good light diffusing that unevenness of brightness is few, thus the present invention finished.
