Embodiment
Below, the present invention is described in detail.
Anti-dazzle film of the present invention comprises transparent base and antiglare layer, above-mentioned antiglare layer above-mentioned transparent base one side or two-sided on be coated with anti-glare coating composition and formed.Now, preferably, the diffuse reflectance (Rd) that above-mentioned anti-dazzle film is represented by following mathematical expression 1 is less than 0.5%.
(mathematical expression 1)
Diffuse reflectance (Rd)=total reflectivity (Rt)-specular reflectance (Rp)
(in above-mentioned mathematical expression 1, total reflectivity is the overall ratio of the reflected light reflected towards all directions, and specular reflectance is with the ratio of the reflected light of the angle mirror-reflection identical with incident angle.）
In foregoing, the total reflectivity (Rt) that diffuse reflectance is defined as the overall ratio of the reflected light reflected towards all directions deducts with the value of the specular reflectance (Rt) of the ratio of the reflected light of the angle mirror-reflection identical with incident angle.According to above-mentioned definition, if diffuse reflectance is little, then show towards the ratio of the light of mirror-reflection direction reflection large, therefore diffuse reflection is not serious.Even if this means reflecting external light, the blackness of anti-dazzle film also can not reduce.On the contrary, if diffuse reflectance is large, then show towards the ratio of the light of mirror-reflection direction reflection little, therefore diffuse reflection is serious, and blackness can reduce thus.
Therefore, in order to provide the display device with high blackness and contrast excellence, the diffuse reflectance of anti-dazzle film is more low more favourable, and preferably, the diffuse reflectance of anti-dazzle film is less than 0.5%, is more preferably less than 0.2%.
The diffuse reflectance recorded in the present invention more can correctly show blackness and anti-glare than the mist degree (%) of the light characteristic of ordinary representation anti-dazzle film.This shows difference in its measuring principle and method.That is, for the mist degree (%) usually measured in anti-dazzle film, generally measure in the transmission mode, ask the formula of mist degree to represent with the ratio of scattering transmissivity with overall transmissivity.In this formula, scattering transmissivity is by specify at JIS(Japanese industry) etc. the light of the above scattering of angle of regulation reflect towards integrating sphere and try to achieve.
Be summarized as follows with the difference of diffuse reflectance that specifies in the present invention in this section.Mist degree is tried to achieve by transmissivity, and the mist degree being therefore difficult to distinguishing assay is the impact of the externals stray of concave-convex surface based on anti-dazzle film, or based on the impact of coating layer scattering-in.Thus, even have the anti-dazzle film of identical mist degree, scattering-in and the externals stray based on concave-convex surface different separately, therefore frequently appear at the situation being visually regarded as distinct film.On the contrary, with regard to the diffuse reflectance related in the present invention, the main reflection measuring anti-dazzle film surface, therefore high with the consistent degree of actual visual experience.Further, with regard to the scattering transmitted light of mist degree, the region of transmission of always advancing more than special angle exceedingly to miss, thus causes the difference with visual experience.On the contrary, with regard to the diffuse reflectance related in the present invention, irreflexive data comprise all numerical value except specular angle, therefore, it is possible to more critically measure blackness and anti-glare.
But when comprising the anti-glare coating fluid of particle with the coating of general method, according to its thickness, although make the size of concave-convex surface part adjusted to a certain extent, diffuse reflectance is difficult to be shown as less than 0.5%.
In the present invention in order to realize this purpose, when forming antiglare layer, use special method that the lower area that there is light transmission particle is separated with the upper area that there is not light transmission particle.Multiple method can be used for realizing this purpose.Such as, after carrying out first time coating with the anti-glare coating fluid comprising light transmission particle, carry out second time coating on top with the transparent coating solution not comprising particle, thus can said structure be obtained.As another one example, after coating comprises the anti-glare coating fluid of light transmission particle, postpone solvent evaporation process, thus also can reach said structure with the method for sedimentation light transmission particle in coating layer.The method of above-mentioned delay solvent evaporation process has the method using high boiling solvent and the method reducing dry air quantity and temperature.
As other physical methods, the method for bottom light transmission particle being induced to coating layer can be used.After making to comprise in light transmission particle the material reacted with magnetic field or electric field, after coating anti-glare coating fluid, apply the bottom that particle is induced to coating layer by magnetic field or electric field, thus can said structure be obtained.
That is, in order to improve anti-glare and blackness simultaneously, need to adjust the coating shape of anti-glare coating composition for the formation of antiglare layer and antiglare layer simultaneously.
