[0062] [Structure of antifouling base material]

[0063] figure 1 A is a cross-sectional view showing an example of the configuration of the antifouling substrate according to the first embodiment of the present technology. Such as figure 1 As shown in A, the antifouling substrate (antifouling body) has a fingerprint-resistant surface (antifouling surface) S having a fingerprint-resistant function. The anti-fingerprint surface S contains a compound having a specific molecular structure described later, and has a protrusion-like fine structure on the surface. Therefore, the fingerprints adhering to the fingerprint-resistant surface S spread wet anyway, and are not easily seen. In addition, when the protrusion-like fine structure is set to a predetermined height, excellent wiping properties can also be obtained.

[0064] The antifouling base material includes a base material 11 and an antifouling layer 12 provided on the surface of the base material 11 . Here, although an...

no. 2 Embodiment approach ＞

[0195] Figure 10 It is a cross-sectional view showing an example of the configuration of the antifouling substrate according to the second embodiment of the present technology. Such as Figure 10 As shown, this antifouling base material is different from the first embodiment in that the base material 21 and the plurality of protrusions 22 are integrally formed. As the material of the base material 21 and the protrusion 22, the same material as that of the antifouling layer 12 in the first embodiment described above is used. Specifically, as a material of the base material 21 and the protrusion 22, a material containing a thermoplastic resin composition is preferable. In this case, the thermoplastic resin composition preferably contains at least one of the first compound and the second compound. The base material 21 and the protrusion 22 are the same as the base material 11 and the protrusion 12a in the first embodiment described above except for the constituent materials. ...

Abstract

This antifouling body has a surface such that when a fingerprint has adhered to the surface, the pattern of the fingerprint wets and spreads spontaneously to result in an indistinct state. The surface is provided with multiple protrusions. Each protrusion contains a first compound which has an ester bond at a site other than the terminals and / or a second compound which has a cyclic hydrocarbon group.

Description

technical field [0001] The present technology relates to an antifouling body, a display device including the antifouling body, an input device, electronic equipment, and an antifouling article. Specifically, it relates to an antifouling body that suppresses surface fouling. Background technique [0002] In recent years, information display devices equipped with a touch panel as a user interface (UI) have rapidly spread. The touch panel has the advantage that the device can be operated intuitively by directly touching the display screen with a finger, but on the other hand, there is a problem that the visibility of the screen is deteriorated due to the adhesion of fingerprints. Therefore, there is a demand for a fingerprint-resistant surface that does not easily see fingerprints even if they adhere. [0003] Conventionally, an antifouling layer is used on the surface of a display including a touch panel, and the antifouling layer is designed so that a fluorine-based compoun...
