In addition, the first substrate 102 may be a polarizing plate. That is, the second sensing electrode 220 may be formed on the upper surface or the back surface of the polarizer. Accordingly, the second sensing electrode and the polarizing plate may be integrally formed.

In addition, the first substrate 102 may further include a polarizing plate. At this time, the polarizing plate may be disposed below the first substrate 102. For example, the polarizing plate may be disposed between the first substrate 102 and the display panel. The polarizing plate may be disposed on the first substrate 102.

When the display panel is a liquid crystal display panel, when the sensing electrode is formed on the first substrate 2100, the sensing electrode may be formed with a thin film transistor (TFT) or a pixel electrode. In addition, when the sensing electrode is formed on the back surface of the second substrate 2200, a color filter layer may be formed on the sensing electrode, or a sensing electrode may be formed on the color filter layer. When the display panel is an organic light emitting display panel, when the sensing electrode is formed on the upper surface of the first substrate 2100, the sensing electrode may be formed with a thin film transistor or an organic light emitting diode.

Hereinafter, an example of a display device to which a touch window according to the above-described embodiments is applied will be described with reference to FIGS.

Referring to Fig. 13, a mobile terminal is shown as an example of a touch device. The mobile terminal 1000 may include a valid area AA and a non-valid area UA. The effective area AA senses a touch signal by touching a finger or the like, and a command icon pattern part and a logo are formed on the non-valid area.

Referring to FIG. 14, the touch window may include a flexible flexible touch window. Accordingly, the touch device device including the same may be a flexible touch device device. Therefore, the user can bend or bend by hand.

Referring to FIG. 15, such a touch window can be applied not only to a touch device such as a mobile terminal, but also to a car navigation system. 16, such a touch window can also be applied to a vehicle. That is, the touch window can be applied to various parts to which a touch window can be applied in the vehicle. Therefore, not only PND (Personal Navigation Display) but also dashboard can be applied to implement CID (Center Information Display). However, the embodiment is not limited thereto, and it goes without saying that such a touch device device can be used for various electronic products.
