Abstract

A slim type touch panel is provided. The slim type touch panel includes an upper substrate, a first sensor electrode layer disposed at a lower part of the upper substrate, an insulating film disposed at a lower part of the first sensor electrode layer, and a second sensor electrode layer disposed at a lower part of the insulating film, or includes a first sensor electrode cover sheet in which a sensor electrode layer is patterned, a first adhesive layer disposed at a lower part of the first sensor electrode cover sheet, and a film layer disposed at a lower part of the first adhesive layer and comprising a second sensor electrode layer.

Claims

1. A mobile terminal comprising a slim type touch panel, the mobile terminal comprising:

a first sensor electrode cover sheet in which a first sensor electrode layer is patterned, the first sensor electrode cover sheet comprising;

an upper substrate,

a first sensor electrode layer patterned in a lower part of the upper substrate, and

a transparent protective layer disposed at a lower part of the first sensor electrode layer;

a first adhesive layer disposed at a lower part of the first sensor electrode cover sheet, the first adhesive layer being formed with an adhesive material supporting an adhesive function;

a film layer disposed at a lower part of the first adhesive layer and comprising a second sensor electrode layer;

a second adhesive layer disposed at a lower part of the film layer;

a display panel disposed at a lower part of the second adhesive layer; and

a dummy pattern layer formed with a same material as that of the first sensor electrode layer in a portion of upper substrate in which the first sensor electrode layer is not formed and connected to signal lines to output an antenna signal.

2. The mobile terminal of claim 1, further comprising an insulating layer disposed between the upper substrate and the first sensor electrode layer.

3. The mobile terminal of claim 1, further comprising:

a dummy pattern for penetrating at least one sensor electrode line comprised in the first sensor electrode layer and the second sensor electrode layer and having a plurality of holes having at least one shape of a polygon matrix, an oval matrix, and a stripe,

wherein the dummy pattern layer has at least one shape of a polygon matrix, an oval matrix, and a stripe.

4. The mobile terminal of claim 1, wherein at least one set of the first sensor electrode cover sheet, the first adhesive layer, the film layer, and the second adhesive layer are integrally formed.

5. A slim type touch panel comprising:

a first sensor electrode cover sheet in which a first sensor electrode layer is patterned, the first sensor electrode cover sheet comprising;

an upper substrate;
