no. 1 Embodiment approach
[0046] figure 1 It is a schematic cross-sectional view showing a substrate with an antiglare film according to an embodiment of the present invention. figure 1 The shown substrate 1 with an antiglare film has a transparent substrate 2 and an antiglare film 3 arranged on the transparent substrate 2 .
[0047] In the substrate 1 with an antiglare film, the antiglare film 3 mainly contains silica and contains CF 3 (CH 2 ) n - group (where n is an integer of 1 to 6. The same applies hereinafter). In addition, the skewness Rsk of the roughness curve of the surface of the anti-glare film 3 is 1.3 or less, and the arithmetic mean roughness Ra is 0.01 μm or more. By anti-glare film 3 has the above-mentioned characteristics, the substrate 1 with anti-glare film has excellent anti-glare property, and reduces the haze, for example, when observing the black printing layer through the substrate 1 with anti-glare film, it can suppress the observation of white turbid. Hereinafter, each...
no. 2 Embodiment approach
[0152] figure 2 It is a schematic cross-sectional view showing the base body 10 with an anti-glare film according to this embodiment. image 3 It is a schematic bottom view showing the base 10 with an anti-glare film. for figure 2 and image 3 For the substrate 10 with anti-glare film shown in figure 1 The anti-glare film 3 of the base body 1 with the anti-glare film shown is equipped with a low reflection film 4 and an anti-fouling film 5, and a printing layer is provided on the peripheral portion of the surface opposite to the anti-glare film 3 of the base body 1 with an anti-glare film. 6. In this point, it is different from the base body 1 with anti-glare film, but other configurations are common. Therefore, in the base body 10 with an anti-glare film, the components corresponding to the base body 1 with an anti-glare film are assigned the same reference numerals, and detailed description thereof will be omitted. In addition, all of the low-reflection film 4, the an...
Embodiment 1
[0188] Hereinafter, although an Example is shown and this invention is demonstrated in detail, it is not limited to the following Example. Among Examples 1 to 28, Examples 1 to 17 are examples, and Examples 18 to 28 are comparative examples.
[0189] The evaluation methods and materials used in each example are as follows.
[0190]
[0191] (Skewness Rsk of roughness curve, arithmetic mean roughness Ra, average length RSm of roughness curve elements)
[0192] Using SURFCOM1500SD3-12 manufactured by Tokyo Precision Co., Ltd., according to the method specified in JIS B0601-2001, the skewness Rsk of the roughness curve, the arithmetic average roughness Ra, and the average length RSm of the roughness curve elements on the surface of the anti-glare film were respectively tested. Determination.
[0193] (average film thickness)
[0194] The film thickness of the antiglare film was measured as follows. The cross-section of the anti-glare film processed by focused ion beam proce...
