Abstract

Disclosed is a touch display device capable of improving resolution and visibility. The touch display device is configured such that a display electrode in a display panel and a touch-sensing electrode located on a top of the display panel are inclined at the same angle in the same direction.

Claims (10)

1. A touch display device comprising:

a display panel including a pixel electrode located in each of a plurality of pixel areas;

a gate line and a data line crossing each other in each of the plurality of pixel areas; and

a touch-sensing electrode located on top of the display panel for sensing whether a user touch occurs,

wherein the pixel electrode and the touch-sensing electrode are inclined at a same angle, which is lower than 10 degrees relative to the gate line in a same direction,

wherein the touch-sensing electrode has a plurality of inclined touch slits in a shape of “/” or “\” and the plurality of touch slits are all inclined in a same direction,

wherein the pixel electrode has a plurality of display slits in a shape “<” or “>,” and the plurality of touch slits are arranged in parallel to any one of two inclination directions of each of the plurality of display slits, and

wherein the pixel electrode is exposed through a contact hole and formed on a protective film covering a common electrode located in the plurality of pixel areas for generating an electric field together with the pixel electrode.

2. The touch display device according to claim 1 , wherein the pixel electrode has a side surface exposed by the plurality of display slits, and the exposed side surface is inclined at an angle lower than 10 degrees relative to the gate line, and

wherein the touch-sensing electrode has a side surface exposed by the plurality of touch slits, and the exposed side surface is inclined at an angle lower than 10 degrees relative to the gate line.
