Description
The present invention relates to a light diffusing anti-glare film composition and a light-diffusion anti-glare film using the same, and more particularly, a composition for light-diffusion anti-glare film that can be used in the manufacture of a light-diffusion anti-glare film excellent in front transmittance and slope diffusion sharpness, A light diffusion antiglare film formed using the same, a polarizing plate and a liquid crystal display device provided with the light diffusion antiglare film.
In recent years, the liquid crystal display device is rapidly expanding the application range of mobile phones, personal computer monitors, televisions, liquid crystal projectors, and the like. In general, a liquid crystal display device operates a liquid crystal in display modes such as twisted nematic (TN) mode, vertical alignment (VA) mode, and in-plane switching (IPS) mode, and electrically controls light passing through the liquid crystal. A character or an image is displayed by showing the difference of contrast on a screen.
Conventionally, in the liquid crystal display device, there is a problem that high contrast cannot be obtained when the display screen is viewed from an oblique direction, and that good display characteristics cannot be obtained due to a gray level inversion phenomenon in which the contrast of an image is reversed, that is, a narrow viewing angle. It has been pointed out.
As a method for solving the above problems, a technique for providing a light diffusing anti-glare film on the visual side of the liquid crystal display device is known. For example, the light-diffusion anti-glare film (light-diffusion sheet) which has a high haze light-diffusion layer formed by apply | coating the coating liquid containing microparticles | fine-particles on a base material is well known. By arranging such a light-diffusion antiglare film on the viewing side surface of the liquid crystal display device, when viewing the display screen of the liquid crystal display device at an angle, it is possible to extend the viewing angle by reducing the contrast of the image or improving the gray level inversion phenomenon.
However, in the conventional light-diffusion antiglare film, when sufficient light diffusivity is provided to obtain a wide viewing angle, the transmission sharpness of the display image is lowered, and thus the front contrast of the display image is lowered, and the surface of the light diffusion layer is reduced. There was a problem that the so-called whitening that caused the entire screen to appear white due to diffuse reflection occurred. On the contrary, if it was intended to provide sufficient transmission sharpness, the light diffusivity was insufficient and a wide viewing angle could not be obtained (see Japanese Patent Laid-Open No. 2012-48223).
The present invention is to solve the above problems, one object of the present invention is to provide a composition for light-diffusion anti-glare film that can be used in the production of a light-diffusion anti-glare film excellent in front transmission sharpness and slope diffusion sharpness.
Another object of the present invention is to provide a light diffusing antiglare film formed using the composition for light diffusing antiglare film.
Still another object of the present invention is to provide a polarizing plate provided with the light diffusion antiglare film.
Still another object of the present invention is to provide a liquid crystal display device having the light diffusing antiglare film.
On the other hand, the present invention provides a light diffusing anti-glare film composition having a front transmissive vividness of 100% or more, the slope diffusion sharpness of 200% or more.
In one embodiment of the present invention, the light diffusing anti-glare film is characterized in that the haze is 80 to 90%.
The composition for light-diffusion anti-glare film which concerns on one Embodiment of this invention is characterized by including a silicone particle, a translucent resin, an initiator, and a solvent.
On the other hand, the present invention provides a light-diffusion anti-glare film is formed on one side or both sides of the transparent substrate, the light-diffusion layer comprising a cured product of the composition for light-diffusion anti-glare film is formed.
On the other hand, the present invention provides a polarizing plate characterized in that the light-diffusion anti-glare film is provided.
On the other hand, the present invention provides a liquid crystal display device characterized in that the light diffusion anti-glare film is provided.
The light-diffusion anti-glare film according to the present invention has high haze and excellent front transparence and slope diffusivity. In addition, the liquid crystal display device including the light diffusing anti-glare film according to the present invention can remove the backlight diffusion film to prevent scratches generated on the surface of the backlight side polarizer due to the backlight diffusion film.
Hereinafter, the present invention will be described in more detail.
One embodiment of the present invention relates to a light diffusing antiglare film composition having a front transmissivity of at least 100% and a slope diffusivity of at least 200%.
In one embodiment of the present invention, the light diffusing anti-glare film is characterized in that the haze is 80 to 90%.
Said haze and transmission sharpness are prescribed | regulated to JISK 7105-1981 "the optical characteristic test method of plastics", and the method of obtaining the haze itself is also prescribed | regulated to JIS K 7136: 2000 "the method of obtaining the haze of a plastic-transparent material". It is. Haze is a value defined by following formula (1).
[Equation 1]
Haze = (diffusion transmittance / total light transmittance) * 100 (%)
On the other hand, the transmission sharpness means the image sharpness measured by the transmission method. As defined in the above specification, the image clarity is a value obtained according to Equation 2 below from the highest crest and the lowest crest recorded on the recording paper when any optical light is used. In addition, in this specification, the average value of the measurement result of the vertical direction and the horizontal direction of the test piece was employ | adopted.
[Equation 2]
Image Clarity = [(Highest Digging-Lowest Digging) / (Highest Digging + Lowest Digging)] × 100 (%)
In the above standard, as optical light used for measuring image sharpness, four types of ratios of the width of the dark portion and the ridge are 1: 1, and the widths are 0.125 mm, 0.5 mm, 1.0 mm, and 2.0 mm are defined. In the above, the four types of optical light are used to determine the transmission clarity with the total value of the image clarity measured by the transmission method. Thus, since the total value of the value measured using four types of optical light is made into transmission sharpness, the maximum value, ie, the value (total value of) measured without a sample, becomes 400%.
