Abstract

Disclosed herein is a touch panel including a glass cover, a light transmitting conductive film, a flexible circuit board, a light blocking print layer, and a colored print layer.

Claims (27)

1. A touch panel comprising:

a cover member having a first face side and a second face side, the first face side being an inputting face side and the second face side being opposite to the first face side;

a conductive member that is formed on the second face side of the cover member, and that configures input position detecting electrodes in an inputting region;

a mounting terminal in a mounting region existing in a peripheral region that is outside the inputting region in a plan view;

a plurality of peripheral wiring lines disposed in the peripheral region, the peripheral wiring line each having a first end electrically connected to the mounting terminal and a second end connected to one of the input position detecting electrodes;

a first light blocking layer formed on the second face side of the cover member so as to cover at least a part of the peripheral wiring lines when viewed from the first face side of the cover member; and

a second light blocking layer formed between the cover member and the peripheral wiring line,

wherein the first light blocking layer overlaps at least a part of the second light blocking layer so as to partly sandwich the peripheral wiring lines between the first light blocking layer and the second light blocking layer.

2. The touch panel according to claim 1 , wherein input position detecting electrodes are touch detecting electrodes of a capacitance type.

3. The touch panel according to claim 2 , wherein the touch detecting electrodes are configured to detect a position of touch and include:

first detecting electrodes arranged extending in a first direction; and

second detecting electrodes arranged extending in a second direction crossing the first direction.

4. The touch panel according to claim 3 , wherein the first detecting electrodes and the second detecting electrodes are disposed in a same layer configured by the conductive member.

5. The touch panel according to claim 4 , wherein

the peripheral wiring lines are disposed in the same layer with the first detecting electrodes and the second detecting electrodes, and

each of the peripheral wiring lines is connected to one of the first electrodes and the second electrodes.

6. The touch panel according to claim 1 , wherein

the mounting terminal is a flexible circuit board, and

the first light blocking layer covers a portion of the flexible circuit board which overlaps the cover member.

7. An electro-optical apparatus including an image production apparatus and a touch panel, the touch panel comprising:

a cover member having a first face side and a second face side, the first face side being an inputting face side and the second face side being opposite to the first face side;

a conductive member that is formed on the second face side of the cover member, and that configures input position detecting electrodes in an inputting region;

a mounting terminal in a mounting region existing in a peripheral region that is outside the inputting region in a plan view;

a plurality of peripheral wiring lines disposed in the peripheral region, the peripheral wiring line each having a first end electrically connected to the mounting terminal and a second end connected to one of the input position detecting electrodes;

a first light blocking layer formed on the second face side of the cover member so as to cover at least a part of the peripheral wiring lines when viewed from the second face side of the cover member; and

a second light blocking layer formed between the cover member and the peripheral wiring line,

wherein the first light blocking layer overlaps at least a part of the second light blocking layer so as to partly sandwich the peripheral wiring lines between the first light blocking layer and the second light blocking layer.
