[0183] "Formation of Mask Layer"

[0184] [Preparation of photosensitive film K1 for mask layer formation]

[0185] On a polyethylene terephthalate film temporary support body having a thickness of 75 μm, a coating liquid for a thermoplastic resin layer containing the following formulation H1 was applied and dried using a slit nozzle. Next, a coating liquid for an intermediate layer containing the following formulation P1 was applied and dried. Furthermore, the coating liquid for black photocurable resin layers containing the following formulation K1 was apply|coated and dried. In this way, on the temporary support, a thermoplastic resin layer with a dry film thickness of 15.1 μm, an intermediate layer with a dry film thickness of 1.6 μm, and a black photocurable resin layer with a dry film thickness of 2.2 μm are provided so that the optical density is 4.0. The resin layer is finally crimped with a protective film (polypropylene film with a thickness of 12 μm). In this man...

Abstract

Provided is a method for producing a capacitive input device which comprises a front plate and, provided on a non-contact side of the front plate, (1) a mask layer, (2) a plurality of first transparent electrode patterns, (3) a plurality of second transparent electrode patterns, (4) an insulation layer which electrically insulates the first transparent electrode patterns and the second transparent electrode patterns, and (5) a conductive element which is electrically connected to the first transparent electrode patterns and / or the second transparent electrode patterns and which is different from the first transparent electrode patterns and the second transparent electrode patterns, wherein a photosensitive film comprising a provisional support, a thermoplastic resin layer, and a photo-curable resin layer in that order is used to form at least one of (1) to (5). A high quality capacitive input device can be produced by these simple steps.

Description

technical field [0001] The present invention relates to a method of manufacturing a capacitive input device capable of detecting the contact position of a finger as a change in capacitance, a capacitive input device obtained by the manufacturing method, and a configuration comprising the capacitive input device The image display device of the element. Background technique [0002] In electronic devices such as mobile phones, car navigations, personal computers, ticket vending machines, and bank terminals, in recent years, tablet-type input devices have been arranged on the surfaces of liquid crystal devices and the like. Information corresponding to the pointing image is input by touching the portion where the pointing image is displayed with a finger or a stylus pen on the pointing image in the image display area. [0003] Such an input device (touch panel) includes a resistive film type, an electrostatic capacitive type, and the like. However, the resistive film-type inp...
