Abstract

A manufacture method for display device includes the steps of: (a) forming a metal film on a substrate; (b) forming a metal layer by patterning the metal film; and (c) following the step (b) and forming, on the metal layer, a low reflection layer of a resin. The step (b) includes the steps of: (b1) forming an etching protection film; (b2) patterning the etching protection film; and (b3) following the step (b2) and etching the metal film.

Claims (20)

1. A display device comprising:

an array substrate; and

a counter substrate including a light shielding layer,

wherein the array substrate comprises:

display pixel electrodes; and

scanning electrodes for touch panel extended in a first direction,

the counter substrate comprises:

a substrate having an first surface opposed to the array substrate, and a second surface on the opposite side from the first surface; and

detection electrodes for touch panel extended in a second direction different from the first direction,

one detection electrode of the detection electrodes comprises:

a metal layer disposed on the second surface of the substrate: and

a low reflection layer disposed on the metal layer,

the metal layer contains an aluminum alloy,

the low reflection layer is formed of an UV-bleaching resin, which becomes able to be impregnated with a pigment dispersed by irradiation of UV light, and

the one detection electrode is formed in a zigzag pattern.

2. The display device according to claim 1 , wherein the low reflection layer contains a pigment.

3. The display device according to claim 2 , further comprising a resin layer covering side surfaces of the metal layer.

4. The display device according to claim 1 , wherein the low reflection layer contains a dye.

5. The display device according to claim 4 , further comprising a protection layer for covering the metal layer and the low reflection layer.

6. The display device according to claim 1 , further comprising a protection layer for covering the metal layer and the low reflection layer.
