Abstract

A display device is disclosed. In one embodiment, the device includes: i) a display panel having a display area and a peripheral area, ii) a touch panel disposed corresponding to the display area on the display panel, iiii) a connecting portion extending from an edge of the touch panel to an edge of the display panel and iv) a window disposed on the touch panel, and including a window main body covering the display area and the peripheral area and a black matrix portion covering the peripheral area. The device may further include a resin layer disposed between the window and the touch panel and cured with light and a reinforcing tape attached to the peripheral area of the display panel and attached between the connecting portion and the display panel, and having a groove recessed corresponding to the connecting portion.

Claims (20)

1. A display device comprising:

a display panel comprising a display area and a peripheral area;

a touch panel placed substantially corresponding to the display area on the display panel;

a connecting portion extending from an edge of the touch panel to an edge of the display panel;

a window placed on the touch panel, wherein the window comprises i) a window main body covering the display area and the peripheral area and ii) a black matrix portion covering the peripheral area;

a resin layer formed between the window and the touch panel, wherein the resin layer directly contacts the black matrix portion; and

a reinforcing tape attached to the peripheral area of the display panel and attached between the connecting portion and the display panel, wherein a groove, recessed substantially corresponding to the connecting portion, is formed in the reinforcing tape, and

wherein the resin layer is closer to the reinforcing tape than the window.

2. The display device of claim 1 , wherein the display panel comprises:

a first substrate having a first width; and

a second substrate disposed on the first substrate and having a second width less than the first width, wherein the reinforcing tape is attached to the first substrate exposed to the second substrate.

3. The display panel of claim 2 , wherein a first height measured from the upper surface of the first substrate to the upper surface of the reinforcing tape substantially corresponding to the groove is less than a second height measured from the upper surface of the first substrate to the upper surface of the second substrate.

4. The display device of claim 3 , wherein a third height measured from the upper surface of the first substrate to the upper surface of the reinforcing tape is greater than the second height.

5. The display device of claim 1 , wherein a first light transmitted through the window is configured to cure the resin layer substantially corresponding to the display area, and

wherein a second light irradiated onto a side of the display panel is configured to cure the resin layer substantially corresponding to the peripheral area.

6. The display device of claim 1 , wherein the display device further comprises a driver disposed on the back surface of the display panel and connected to the connecting portion passed through the edge of the display panel.

7. The display device of claim 6 , wherein the connecting portion includes a flexible printed circuit board (FPCB).

8. The display device of claim 1 , wherein the display panel includes liquid crystal or an organic light emitting diode.

9. The display device of claim 1 , wherein the light has a wavelength of the ultraviolet spectrum.

10. The display device of claim 1 , wherein the resin layer is continuously formed.
