Abstract

An input device includes a substrate having a first main surface and a second main surface located opposite to the first main surface; a protective member having an opposed surface opposite to the first main surface; a bonding member configured to bond the first main surface and the opposed surface to each other; a first coloring member disposed between the first main surface and the opposed surface, the first coloring member being in contact with the bonding member; and a second coloring member disposed on the second main surface and having a color different from a color of the first coloring member.

First claim

The invention claimed is:

1. An input device, comprising:
a substrate having a first main surface and a second main surface located opposite to the first main surface;
a first protective member having a first opposed surface opposite to the first main surface;
a second protective member having a second opposed surface opposite to the second main surface;
a first bonding member configured to bond the first main surface and the first opposed surface to each other;
a second bonding member configured to bond the second main surface and the second opposed surface to each other;
a first coloring member disposed between the first main surface and the first opposed surface, the first coloring member being in contact with the first bonding member; and
a second coloring member disposed on the second main surface, the second coloring member being in contact with the second bonding member, and having a color different from a color of the first coloring member.

2. The input device according to claim 1 , wherein the input device includes an input area and an outer area located outside the input area,
wherein the first coloring member is disposed between the first main surface and the first opposed surface in the outer area, and
wherein the second coloring member is disposed on the second opposed surface in the outer area.

3. A display device, comprising:
the input device according to claim 1 ; and
a display panel disposed to face the input device.

4. The display device according to claim 3 , wherein the display panel is a liquid crystal display panel.
