Abstract

Provided is a display device integrated with a touch screen panel including a display unit including a plurality of pixels at a sealed region between a lower substrate and an upper substrate; first touch electrodes extending in a first direction on the upper substrate over the sealed region, wherein ends of the first touch electrodes extend to a non-sealed region on the lower substrate; and a sloped portion beneath the first touch electrodes at a boundary between the sealed region and the non-sealed region.

Claims

1. A display device integrated with a touch screen panel comprising:

a display unit comprising a plurality of pixels at a sealed region between a lower substrate and an upper substrate;

first touch electrodes extending in a first direction on an upper surface of the upper substrate over the sealed region, the upper surface of the upper substrate facing away from the display unit, and ends of the first touch electrodes extending to a non-sealed region on the lower substrate; and

a sloped portion extending from one end of the upper substrate to be integral with the upper substrate at a boundary between the sealed region and the non-sealed region, the sloped portion being beneath the first touch electrodes and filling an area between the lower substrate and the upper substrate at the boundary between the sealed region and the non-sealed region.

2. The display device of claim 1, wherein the first touch electrodes extend from a region over the sealed region on the upper substrate to the non-sealed region on the lower substrate via an upper side of the sloped portion.

3. The display device of claim 1, wherein the first touch electrodes have a line shape, and the first touch electrodes extend from a region over the sealed region on the upper substrate to the non-sealed region on the lower substrate via an upper side of the sloped portion.

4. The display device of claim 1, wherein pads of the first touch electrodes are at the non-sealed region on the lower substrate so as to be with pads for driving the pixels of the display device.

5. The display device of claim 1, wherein the sloped portion is formed by patterning the one end of the substrate, at the boundary between the sealed region and the non-sealed region, to be sloped.

6. The display device of claim 1, further comprising second touch electrodes extending in a second direction intersecting the first direction, and facing the first touch electrodes.

7. The display device of claim 6, wherein the second touch electrodes are foimed at the sealed region.

8. The display device of claim 7, further comprising outer lines coupled to the second touch electrodes and extending from the sealed region to the non-sealed region on the lower substrate,

wherein pads coupled to the outer lines are aligned with pads of the first touch electrodes.

9. The display device of claim 6, wherein the second touch electrodes are formed by patterning at least one electrode selected from electrodes constituting each pixel.

10. The display device of claim 9, wherein the second touch electrodes are formed by patterning a cathode electrode or a common electrode.

11. The display device of claim 1, further comprising second touch electrodes extending in a second direction intersecting the first direction on the lower substrate.
