Abstract

A display device with a touch panel includes the touch panel having a first substrate having a detection area to detect a coordinate and an outside area in which at least one external terminal is formed, a plurality of first lines to detect the coordinate in the detection area, a plurality of second lines to detect the coordinate in the detection area, wherein each of the plurality of first lines traverse each of the plurality of second lines. An organic emitting display panel is arranged under the touch panel, and a circular polarizing plate arranged at a side of the touch panel opposite to the organic emitting display panel. The organic emitting display panel, the touch panel, and the circular polarizing plate are arranged in this order.

Claims

1. A display device with a touch panel comprising:

the touch panel including a first substrate having a detection area to detect a coordinate and an outside area in which at least one external terminal is formed, a plurality of first lines to detect the coordinate in the detection area, a plurality of second lines to detect the coordinate in the detection area, each of the plurality of first lines traversing each of the plurality of second lines;

an organic emitting display panel under the touch panel; and

a circular polarizing plate arranged at a side of the touch panel opposite to the organic emitting display panel;

wherein the organic emitting display panel, the touch panel, and the circular polarizing plate are arranged in this order.

2. A display device with a touch panel according to claim 1, wherein each of the plurality of second lines and the plurality of first lines is made of metal;

and

wherein each of the plurality of first lines is black in color.

3. A display device with a touch panel according to claim 2, wherein the touch panel includes a plurality of wiring groups;

wherein each of plurality of wiring groups has some of the first lines; and

wherein some of the first lines in each of plurality of wiring groups are bonded with each other.

4. A display device with a touch panel according to claim 3,

wherein a transparent conductive film overlays the plurality of the first lines, and

wherein the transparent conductive film is electrically connected to the plurality of the first lines.

5. A display device with a touch panel according to claim 3,

wherein a transparent conductive film underlays the plurality of the first lines, and

wherein the transparent conductive film is electrically connected to the plurality of the first lines.

6. A display device with a touch panel according to claim 2,

wherein a transparent conductive film overlays the plurality of the second lines;

and

wherein the transparent conductive film is electrically connected to the plurality of the second lines.

7. A display device with a touch panel according to claim 2, wherein a transparent conductive film underlays the plurality of the second lines, and

wherein the transparent conductive film is electrically connected to the plurality of the second lines.

8. A display device with a touch panel according to claim 1,

wherein the touch panel is a resistance-film-type touch panel.

9. A display device with a touch panel according to claim 1, further including:

a first adhesive layer between the touch panel and the organic emitting display panel; and

a second adhesive layer between the touch panel and the circular polarizing plate;

wherein the touch panel and the organic emitting display panel are fixed with each other by the first adhesive layer, and the touch panel and the circular polarizing plate are fixed with each other by the second adhesive layer.
