Problems solved by technology

However, the anti-glare film produced by using such a resin solution in which fine particles are dispersed is difficult to obtain the desired surface roughness because the distribution and shape of the surface irregularities depend on the dispersion state and coating state of the fine particles in the resin solution. , when the haze of the anti-glare film is set low, there is a problem that a sufficient anti-glare effect cannot be obtained
In addition, when such a conventional anti-glare film is arranged on the surface of an image display device, there is a problem that the entire display surface becomes whitish due to scattered light, and the display tends to produce a cloudy color, so-called "whitening".
In addition, with the high-definition of recent image display devices, there is also a problem that the pixels of the image display device and the surface unevenness of the anti-glare film interfere, and as a result, it is easy to cause the brightness distribution to be difficult to see on the display surface. , the so-called "dazzling" phenomenon
As a result, there is a problem that these large uneven shapes interfere with the pixels of the image display device, resulting in brightness distribution, and "glare" that makes it difficult to see the display surface easily occurs.

Embodiment 1

[0139] The coil which gave the copper ballard plating (copper bala-dometsuki) to the surface of the aluminum coil (A5056 based on JIS) of diameter 200mm was prepared. Copper Ballard plating consists of copper plating / thin silver plating / surface copper plating, and the overall thickness of the plating is set at about 200 μm. The copper-plated surface is mirror-polished, and a photosensitive resin is applied to the polished copper-plated surface, followed by drying to form a photosensitive resin film. Next, the pattern data is exposed on the photosensitive resin film by laser light and developed, and the pattern data is the figure 1 Graphic data in which a plurality of gray scale graphic data are continuously and repeatedly arranged. Exposure and development with laser light were performed using Laser Stream FX (manufactured by Think Laboratory). A positive photosensitive resin is used for the photosensitive resin film. figure 1 The grayscale pattern shown is a pattern in whi...

Embodiment 2

[0143] As a grayscale pattern exposed with laser light, use Image 6 A mold B was obtained in the same manner as in Example 1 except that the first etching treatment and the second etching treatment were performed with the etching amount described in Table 1 for the gray scale pattern shown. Except having used the mold B obtained, it carried out similarly to Example 1, and produced the antiglare film B. Image 6 The grayscale graphic data shown is a graphic with multiple dots with a diameter of 12 μm randomly arranged, and the energy spectrum is at a spatial frequency of 0.056 μm -1 presents the maximum value. in addition, Image 6 The grayscale pattern data shown is made into a square with a side of 100 mm.

Embodiment 3

[0145] As a gray scale pattern exposed with laser light, the pattern data is made into a square with a side length of 16 mm. In addition, the same gray scale pattern as that used in Example 1 is used except that described in Table 1. Amount of Etching Except having performed the 1st etching process and the 2nd etching process, it carried out similarly to Example 1, and obtained the mold C. Except having used the mold C obtained, it carried out similarly to Example 1, and produced the antiglare film C.

Abstract

The invention provides a producing method of anti-dizziness film and anti-dizziness film mold, and gray scale grade figure for the producing method. The producing method of an anti-dizziness film comprises the process of forming a concavo-convex surface on a transparent base material based on the gray scale grade figure. The gray scale grade figure is characterized in that the smallest edge is over 15mm in length, and the power spectrum is shown the maximum value in the range of 0.025-0.125 Mum-1 in space frequency. The concavo-convex surface is formed by the repetitive structure of a concavo-convex surface unit which is formed by a concavo part and a convex part with respect to the gray scale grade of the gray scale grade figure.

Description

technical field [0001] This invention relates to the manufacturing method of an antiglare (antiglare: antiglare) film, and the antiglare film obtained by this manufacturing method. Moreover, this invention relates to the manufacturing method of the gradation pattern used for the manufacturing method of this antiglare film, and the mold suitably used for the manufacturing method of this antiglare film. Background technique [0002] Image display devices such as liquid crystal displays, plasma display panels, Braun tube (cathode ray tube: CRT) displays, organic electroluminescent (EL) displays, etc., when external light shines on the display surface, the visibility is significantly impaired . At present, in order to prevent the reflection of such external light, in TVs, personal computers, video cameras and digital cameras used outdoors where the external light is strong, and mobile phones that use reflected light to display, images are The surface of the display device is p...
