A shield disposed to cover the rear surface of the window, the shield being formed except for the image to form a translucent image exposed to the outside;
A light source configured to irradiate light toward the image;
A touch sensor disposed between the shield and the light source, the touch sensor configured to sense a touch input for a portion of the window corresponding to the image; And
And a pattern part formed on the touch sensor in a specific pattern and guiding the light so that light emitted from the light source illuminates the image.

The method of claim 1,
The pattern unit includes a diffusion pattern configured to diffuse the light emitted from the light source corresponding to the image.

3. The method of claim 2,
The diffusion pattern is a mobile terminal, characterized in that formed by scratching the area corresponding to the image.

3. The method of claim 2,
The diffusion pattern includes a plurality of dots that are engraved or embossed to correspond to the image.

3. The method of claim 2,
The pattern unit further comprises a light collecting pattern made to collect light emitted from the light source.

The method of claim 5,
The condensing pattern is a mobile terminal, characterized in that the edge of the image is formed by engraving or embossing.

The method of claim 1,
The touch sensor includes:
A first electrode film having first conductive patterns; And
A second electrode film disposed to cover the first electrode film and having second conductive patterns overlapping the first conductive patterns in at least one point in a thickness direction;
At least one of the first and second conductive patterns may include an image sensing pattern configured to sense a touch input for a portion of the window corresponding to the image.

The method of claim 7, wherein
The pattern unit includes a diffusion pattern formed on any one of the first and second electrode film to diffuse the light irradiated from the light source to correspond to the image.

9. The method of claim 8,
The image sensing pattern is formed on one surface of the corresponding first or second electrode film,
The diffusion pattern is formed on the other surface of the corresponding first or second electrode film so as to be spatially separated from the image sensing pattern.

9. The method of claim 8,
The pattern unit further comprises a light collecting pattern formed on the other of the first and second electrode film to collect the light irradiated from the light source.

The method of claim 10,
The diffusion pattern is disposed between the shielding portion and the light collecting pattern to diffuse light collected by the light collecting pattern to correspond to the image.

The method of claim 10,
The image sensing pattern is formed on one surface of the corresponding first or second electrode film,
The condensing pattern is formed on the other surface of the corresponding first or second electrode film so as to be spatially separated from the image sensing pattern.

The method of claim 1,
The image is provided in a plurality of locations along the width direction of the terminal body to provide different images to the outside,
The pattern unit is a mobile terminal, characterized in that formed along the width direction of the terminal body to correspond to the image provided in a plurality of locations.

The method of claim 1,
Further comprising a frame having a seating portion configured to support the window,
And a hole in the seating portion is formed between the light source and the image to define the emission range of the light to correspond to the image.

The method of claim 1,
A display disposed on a rear surface of the window and configured to output visual information through the window;
The touch sensor is a mobile terminal, characterized in that extending to cover the display to detect a touch input for the portion corresponding to the display in the window.
