Problems solved by technology

However, the anti-glare layer contains fluorine-containing compounds, and the contact angle with glycerol triacetate is greater than 43 degrees, so the lipid components from living organisms that are used to form fingerprints attached to the anti-glare layer easily form tiny droplets, This tiny droplet is an important reason why attached fingerprints are seen, and light is diffusely reflected at this tiny droplet, and the point that fingerprints are clearly visible on the surface of the display has not been improved.
Therefore, there is a problem that the visibility of the displayed image on the display is reduced.

Embodiment

[0089] Next, examples of the present invention will be described. First, methods for measuring fingerprint visibility, surface roughness, contact angle, and haze value will be described.

[0090] 1) Fingerprint visibility

[0091] Fingerprints were attached to the surface material 10 for a display, and the visibility was sensory-evaluated on the following four levels by visual observation.

[0092] 4: No fingerprints can be seen at all; 3: Fingerprints can be seen slightly; 2: Fingerprints are relatively thin, but can be seen clearly; 1: Fingerprints can be seen clearly.

[0093] 2) Surface roughness

[0094] Using the surface roughness measuring machine Surfkoda SE4000 manufactured by Kosaka Research Institute, under the conditions of scanning range 1.5mm and scanning speed 0.1mm / s, according to the regulations in JIS B 0601-1994, Ra and Sm.

[0095] 3) Contact angle

[0096] The contact angle was measured from a 4 µl drop using Drop Master 500 manufactured by Kyowa Inte...

manufacture example 1

[0103] In a flask, 500 parts of colloidal silica [manufactured by Nissan Chemical Industry Co., Ltd., trade name: IPA-SR-L, 30% solution of 2-propanol, average particle diameter of 40 nm to 50 nm], 30 parts of γ-propylene Acyloxypropyltrimethoxysilane [manufactured by Shin-Etsu Chemical Co., Ltd., trade name: KBM5103] and 40 parts of distilled water were mixed to obtain a coating solution for modified colloidal silica. Thereafter, heating and reflux (reaction temperature: 80° C.) were performed for 4 hours to perform hydrolysis and condensation reactions. Through this operation, modified colloidal silica (30% solution of 2-propanol, average particle diameter: 55 nm) was obtained.

manufacture example 2

[0105] Colloidal silica manufactured by Nissan Chemical Industries Co., Ltd. under the trade name XBA-ST (30% solution of a mixture of xylene and n-butanol, with an average particle diameter of 10 nm to 15 nm) was used. 1 was reacted to obtain modified colloidal silica (a 30% solution of a mixture of xylene and n-butanol, with an average particle diameter of 20 nm).

Abstract

The present invention relates to a surface material for a display. The surface material (10) for a display has an anti-glare layer (14; 14, 16) provided on a transparent substrate (11), and the anti-glare layer has resin-made concavo-convex portions on the surface. (13). The contact angle of the flat film formed of the above resin with an oleic acid droplet is 60 degrees or less. The present invention also relates to a display having the surface material for a display.

Description

technical field [0001] The present invention relates to a surface material for a display, and a display having the surface material for a display, the surface material for a display is provided on display displays such as glass casings and plastic casings, and image displays such as personal computers, televisions, and mobile phones. surface. Background technique [0002] In this kind of display, if the light from the outside is reflected on the surface (display surface) without scattering, the image will be reflected there, and it is difficult to see the internal image. Diffuse anti-glare film. [0003] However, when using the display, since the finger touches the surface, fingerprints (hereinafter simply referred to as "fingerprints") produced by lipid components derived from living organisms such as sebum will adhere to the surface, and the visibility of the image ( cognition) is easily impaired. For this reason, countermeasures for preventing fingerprints from adherin...
