Abstract

A touch panel includes a first substrate, multiple translucent first electrodes, multiple first wirings, a second substrate, multiple translucent second electrodes, multiple second wirings, and a light-shielding layer. The first wirings include first ends connected to the respective first electrodes, and second ends extending to the edge of the first substrate. The second wirings include first ends connected to the respective second electrodes, and second ends extending to the edge of the second substrate. The light-shielding layer is formed on the first substrate in a position covering at least a part of the first wirings and also corresponding to at least a part of the second wirings.

Claims (33)

1 . A touch panel comprising:

a first substrate;

a plurality of translucent first electrodes formed on the first substrate in a first direction;

a plurality of first wirings, each including a first end connected to each of the plurality of first electrodes and a second end extending to an edge of the first substrate;

a second substrate disposed below the first substrate;

a plurality of translucent second electrodes formed on the second substrate in a second direction perpendicular to the first electrodes;

a plurality of second wirings, each including a first end connected to each of the plurality of second electrodes and a second end extending to an edge of the second substrate; and

a light-shielding layer formed on the first substrate in a position covering at least a part of the first wirings and also corresponding to at least a part of the second wirings.

2 . The touch panel of claim 1 , further comprising:

a conductive layer formed on at least a part of the light-shielding layer.

3 . The touch panel of claim 1 ,

wherein the light-shielding layer is formed in a frame shape.

4 . The touch panel of claim 1 ,

wherein the plurality of first wirings and the plurality of second wirings are configured with translucent metal and non-translucent metal, and

the light-shielding layer is formed in an area corresponding to the non-translucent metal of the first wirings and the second wirings.

5 . An input device comprising:

a transparent plate;

a display device; and

a touch panel disposed between the transparent plate and the display device, the touch panel including:

a first substrate;

a plurality of translucent first electrodes formed on the first substrate in a first direction;

a plurality of first wirings, each including a first end connected to each of the plurality of first electrodes and a second end extending to an edge of the first substrate;

a second substrate disposed below the first substrate;

a plurality of translucent second electrodes formed on the second substrate in a second direction perpendicular to the first electrodes;

a plurality of second wirings, each including a first end connected to each of the plurality of second electrodes and a second end extending to an edge of the second substrate; and

a light-shielding layer formed on the first substrate in a position covering at least a part of the first wirings and also corresponding to at least a part of the second wirings.

6 . The input device of claim 5 , further comprising:

a decorative layer formed on the transparent plate.

7 . The input device of claim 6 ,

wherein the light-shielding layer and the decorative layer have a same hue.

8 . The input device of claim 6 , further comprising:

a conductive layer formed on at least a part of the light-shielding layer,

wherein the conductive layer and the decorative layer have a same hue.
