Abstract

A display device according to an embodiment of the present invention includes: a display panel; a touch sensor located on the display panel; and a pointer made of a conductive material that moves on a region where the touch sensor is provided below the touch sensor; wherein the pointer is electrically connected to a lower electrode of the touch sensor.

Claims (25)

1. A display device comprising:

a display panel;

a touch sensor located on the display panel; and

a pointer including a conductive material that moves on a region where the touch sensor is provided below the touch sensor; wherein

the pointer is electrically connected to a lower electrode of the touch sensor.

2. The display device according to claim 1 , wherein

the lower electrode of the touch sensor is connected to the pointer through a housing or a conductive wire.

3. The display device according to claim 1 , wherein

the lower electrode of the touch sensor is connected to a ground potential.

4. The display device according to claim 1 , wherein

the display panel comprises:

a substrate,

a plurality of pixels located on the substrate and having a light emitting element;

a display area in which the plurality of pixels are arranged;

a thin film transistor included in each of the plurality of pixels;

a protective film located between the thin film transistor and the light emitting element, and made of an inorganic insulating material; and

a sealing film covering the light emitting element and including an inorganic insulating material, and

the inorganic insulating material included in the sealing film is in contact with the protective film in a first region between the plurality of pixels and a through-hole.

5. The display device according to claim 1 , wherein

the display panel comprises:

a substrate,

a plurality of pixels located on the substrate and having a light emitting element;
