Abstract

A display device includes a display panel including a plurality of pixels, a touch sensor unit provided on the display panel, and including a touch sensing area in which a touch sensor is provided and a non-sensing area around the touch sensing area, and a polarizer provided on the touch sensor unit and bonded to the touch sensor unit, an edge side of the polarizer and an edge side of the touch sensor unit being aligned.

Claims (27)

1. A display device, comprising:

a display panel including a plurality of pixels;

a touch sensor unit provided on the display panel, and including a touch sensing area in which a touch sensor is provided; and

a polarizer provided on the touch sensor unit,

wherein

the touch sensor unit includes a first portion having a first edge and a second portion having a second edge in a plan view, the first edge being connected to the second edge in the plan view,

the first portion overlaps the polarizer, and the first edge of the first portion is aligned with a third edge of the polarizer in the plan view, and

the second portion does not overlap the polarizer, and the second edge of the second portion is not aligned with a fourth edge of the polarizer in the plan view.

2. The display device as claimed in claim 1 , wherein an area of the second portion of the touch sensor unit is defined by the second edge of the second portion and the fourth edge of the polarizer in the plan view.

3. The display device as claimed in claim 1 , wherein:

the touch sensor unit includes a touch wire connected to the touch sensor, and

the touch wire includes an end portion disposed at the second portion of the touch sensor unit that does not overlap the polarizer.

4. The display device as claimed in claim 3 , further comprising a printed circuit film connected to the second portion of the touch sensor unit that does not overlap the polarizer.

5. The display device as claimed in claim 4 , wherein the printed circuit film includes a touch driver connected to the touch sensor unit.

6. The display device as claimed in claim 4 , wherein an edge of the printed circuit film is spaced apart from the fourth edge of the polarizer.

7. The display device as claimed in claim 1 , wherein at least a portion of the fourth edge of the polarizer is parallel to the second edge of the second portion of the touch sensor unit in the plan view.

8. The display device as claimed in claim 1 , further comprising:

a cover window provided on the polarizer,

wherein an edge of the cover window is outside the third and fourth edges of the polarizer, and the cover window covers third and fourth edges of the polarizer.

9. The display device as claimed in claim 8 , wherein:

the touch sensor unit further includes a non-sensing area around the touch sensing area,

the cover window includes a light blocking member covering at least a portion of the non-sensing area, and

the light blocking member covers a lateral side of the display panel.

10. The display device as claimed in claim 1 , wherein the polarizer includes a circular polarizer.

11. The display device as claimed in claim 1 , wherein:

a plurality of touch electrodes are provided in the touch sensing area, and

the plurality of touch electrodes is disposed between a touch substrate and the polarizer or between the touch substrate and the display panel.
