Problems solved by technology

[0003] However, as the colorization of CRTs and FPDs continues to progress, the high-definition of colors in various displays continues to progress. The fine convex shape formed by the fine particles refracts the light from the light source in an unintended direction, causing a dazzling phenomenon called flicker, which causes the problem that the high-definition color screen looks dazzling

Embodiment 1

[0107] A 4 mm-thick copper plate having a smooth surface was cut using a diamond engraving knife to prepare a mold. Into the prepared mold, 50 parts by weight of an acrylic monomer (methyl methacrylate: Wako Pure Chemical Industries, Ltd.) and a polyfunctional acrylic monomer (NKェェステル A-TMPT-3EO : Shin Nakamura Chemical Industry Co., Ltd.) 45 parts of the photopolymerization initiator (Irgacure 184: Ciba Seika Japan Co., Ltd.) 5 parts of the mixed solution, covered with a 100 μm thick polyester film (cosmosh ィ ィン A4300: Toyobo Co., Ltd.), roll The resin is evenly stretched so that no air bubbles remain, so that the resin and the polyester film are tightly bonded.

[0108] In this state, irradiate 1500mJ / cm from the side of the polyester film with a metal halide lamp 2 After the UV-curable resin is cured, the polyester film and the resin are peeled off from the mold, the shape of the mold is faithfully transferred, and the anti-Newton ring sheet of Example 1 ( Figure 5 anti-...

Embodiment 2～10

[0110] The anti-Newton ring sheets of Examples 2-10 were produced similarly to Example 1 except having cut|disconnected the copper plate using the cutting conditions different from Example 1. Table 1 shows the structure of the structure row of the anti-Newton ring sheets of Examples 2-10.

Abstract

Provided is a Newton ring preventing sheet, for example, used for a touch panel that is suitably used on various display screens such as recent high-definition CRT and FPD. Also provided is a touch panel using the same. A Newton ring preventing sheet (1) is configured by arranging a plurality of structural rows (2) in parallel with a pitch (3), and the height of the structural row (2) fluctuates along the extension direction of the ridge thereof. Preferably, the fluctuation of the height of the structural row (2) has periodicity, and the period of the fluctuation falls within the range of 20-4000 [mu]m.

Description

technical field [0001] The present invention relates to an anti-Newton ring sheet, and particularly relates to an anti-Newton ring sheet used for a touch panel used on various display screens such as CRT and FPD, and a touch panel using the same. Background technique [0002] Conventionally, in the fields of photolithography, liquid crystal, and optical equipment, a phenomenon called Newton's rings has occurred due to adhesion between members such as plastic films and glass plates. This Newton ring can be prevented by maintaining the gap generated between the two when the members are in close contact with each other to a certain degree or more. Therefore, it has been proposed to form an anti-Newton ring layer containing a binder component and fine particles on the member. Anti-Newton ring sheet with embossed treatment on one or both sides. [0003] However, as the colorization of CRTs and FPDs continues to progress, the high-definition of colors in various displays continue...
