Embodiment 1

[0097] An ITO film with a thickness of 20 nm was formed on one side of a PET film with a thickness of 0.1 mm by sputtering over the entire surface, and a wide quadrangular shape formed by removing the peripheral portion of the ITO film was used as a transparent electrode. In addition, silver paste was screen-printed to form bus bars arranged on two laterally opposed sides of the transparent electrode and circuits for outputting from the bus bars to the outside. In addition, an acrylic plate having the same length and width as the above-mentioned PET film and a thickness of 0.7 mm is bonded to the surface of the above-mentioned PET film opposite to the surface where the transparent electrode is formed with a transparent adhesive without a base material having a thickness of 0.025 mm. , the fixed electrode substrate 27 on which the transparent electrodes were formed was obtained.

[0098] In addition, a PET film with the same length and width as the main body of the protective p...

Embodiment 2

[0104] The size of the above-mentioned PET base hard coat film is 5 mm larger than the periphery of the main body of the protective panel, and before bonding to the PET film with a thickness of 125 μm, a 0.7-thick acrylic resin film is integrally formed around it by insert molding. mm, a frame body of 5mm wide, otherwise the same as in Example 1.

[0105] According to the obtained protective panel, touch input can be performed on the display window of electronic equipment such as a mobile phone, and the touch input operation surface does not slide on the same part, and dirt such as grease can be easily wiped off.

[0106] In addition, by appropriately combining any of the various embodiments described above, the respective effects can be exhibited.

Abstract

A protection panel (100) for an electronic apparatus display window, having a decoration layer (9) with a protection panel body (1) and a transparent window section (8a) that are made of a transparent resin. The protection panel body (1) is formed from an object on the upper surface of which a transparent lower electrode (2) is formed. The protection panel body (1) is adhered at the peripheral edge section to a transparent resin film (3) on the lower surface of which a transparent upper electrode (4) is formed opposite the transparent lower electrode (2) with an air layer in between. The decoration layer (9) is formed on at least one surface of a transparent resin cover film (8) adhered on the upper surface of the transparent resin film (3).

Description

[0001] technology area [0002] The invention relates to an electronic device with a protective panel, a protective panel for a display window of the electronic device and a manufacturing method for the protective panel for the display window of the electronic device. Background technique [0003] The housings of electronic devices such as mobile phones and smartphones are generally flat housings composed of synthetic resin front housings and rear housings. Specifically, a protective panel for protecting the liquid crystal display window is fixed on the surface of the front case by welding or the like. In addition, the protective panel has conventionally been made of a colorless and transparent resin, but as electronic devices become more fashionable, as disclosed in JP-A-2001-318612, decorations such as borders are applied by printing. In addition, in recent years, mobile phones are expected to have a touch panel as the next interface. As an example of a mobile phone having...
