Problems solved by technology

As a result, there is a problem that these large uneven shapes interfere with the pixels of the image display device, and the so-called glare that is difficult to see easily occurs because of the brightness distribution.

Embodiment 1

[0124] An aluminum coil (A5056 based on JIS) having a diameter of 200 mm on the surface of which copper ballard plating was applied 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. Then, with laser light, the Figure 8 A pattern in which the shown patterns are repeatedly juxtaposed is exposed on the photosensitive resin film and developed. Exposure to laser light and development were performed using Laser Stream FX (manufactured by Think Laboratory Co., Ltd.). A positive photosensitive resin is used for the photosensitive resin film.

[0125] Then, the first etching treatment is performed with copper chloride solution. The etching amount at this time was set to 7 μm. The pho...

Abstract

The invention provides methods of manufacturing an anti-dazzle film and a die for making anti-dazzle film. The method of manufacturing the anti-dazzle film includes forming a fine concavo-convex surface on a transparent supporter on the basis of a pattern provided with plural points with different point diameters in an irregular way, wherein the average point diameter is 6-30 mum, the variation coefficient of the point diameter is 0.1-0.5, and the pattern power spectrum has no maximum in a range of greater 0-1 mum and less than or equal to 0.04-1 mum. Therefore, the anti-dazzle film displays excellent anti-dazzle performance, prevents lowered resolution owing to whitening, does not glare when it is equipped on the surface of a high definition image display device and has a high contrast.

Description

technical field [0001] The present invention relates to a method for producing an antiglare film having low haze and excellent antiglare properties, and a method for producing a mold for obtaining the antiglare film. Background technique [0002] Image display devices such as liquid crystal displays and plasma display panels, Braun tube (cathode ray tube: CRT) displays, organic electroluminescent (EL) displays, etc., when external light shines on the display surface, visibility is significantly impaired. In order to prevent the reflection of such external light, in TVs and personal computers that value image quality, video cameras and digital cameras used outdoors where external light is strong, and mobile phones that use reflected light to display, image display The surface of the device is provided with a film layer to prevent external light from being reflected. The film layer is roughly divided into a film formed by applying a non-reflection treatment using interference...
