Description

Touch window {TOUCH WINDOW}

The embodiment relates to a touch window.

Recently, in various electronic products, a touch window for inputting an image displayed on a display device by contacting an input device such as a finger or a stylus has been applied.

The touch window may be typically divided into a resistive type touch window and a capacitive type touch window. When a pressure is applied to an input device, the resistive touch window detects a change in resistance according to the connection between electrodes, and a position is detected. The capacitive touch window detects a change in capacitance between electrodes when a finger touches it to detect a position. In view of the convenience and sensing power of the manufacturing method, the capacitive method has recently attracted attention in small models.

The touch window may detect a position by disposing a sensing electrode and a wiring electrode connected to the sensing electrode on a substrate, and sensing a change in capacitance when a region in which the sensing electrode is disposed is touched.

Such a touch window may be configured in various types according to the positional relationship of the sensing electrode and/or the wiring electrode.

Recently, in order to reduce the thickness of the touch window, research on arranging an intermediate layer such as a dielectric layer on a substrate and forming an electrode directly on the dielectric layer is underway.

At this time, when connecting the sensing electrode disposed on the dielectric layer and the wiring electrode disposed on the substrate, the adhesion of the connection electrode may be lowered due to a step difference between the dielectric layer and the substrate. There is a problem that the display area decreases due to an increase in the bonding area of the connection electrode.

Accordingly, there is a need for a touch window having a new structure capable of solving the above problems.

An embodiment is intended to provide a touch window that can expand a display area and has improved reliability.

The touch window according to the embodiment includes: a substrate including an effective area and an inactive area; A wiring electrode disposed on the ineffective region; An intermediate layer disposed on the substrate while covering an end of the wiring electrode; A sensing electrode disposed on the intermediate layer; And a connection electrode connecting the sensing electrode and the wiring electrode, wherein the connection electrode connects the sensing electrode and the wiring electrode on the intermediate layer.

The touch window according to the embodiment can increase the effective area, that is, the display area, and improve the reliability of the touch window.

In detail, in the touch window according to the embodiment, since the connection electrode is disposed only on the intermediate layer, the bonding width of the connection electrode can be reduced, and accordingly, reduction of the display area by the connection electrode can be prevented.

In addition, since the touch window according to the embodiment is connected through the sensing electrode and the wiring electrode through the connection electrode on the intermediate layer without a step difference, such a problem can be prevented, thereby improving the reliability of the touch window.
