A display device is provided. The display device includes a first sensing electrode extending in a first direction, the first sensing electrode including a first sub-sensing electrode and a second sub-sensing electrode spaced apart from each other in a touch area which senses a touch input; a second sensing electrode extending in a second direction intersecting the first direction, the second sensing electrode including a third sub-sensing electrode and a fourth sub-sensing electrode spaced apart from each other in the touch area; a first touch signal line connected to the first sub-sensing electrode and the second sub-sensing electrode; and a second touch signal line connected to the third sub-sensing electrode and the fourth sub-sensing electrode.

Display device

A touch sensor includes a base layer including a sensing area and a non-sensing area; and a sensor electrode disposed in the sensing area and including sensor patterns. The sensing area may include a first area including at least one non-square boundary with a predetermined curvature and a second area not including the non-square boundary. In an exemplary embodiment of the present inventive concept, sensor patterns disposed in the first area and sensor patterns disposed in the second area among the sensor patterns may have different sizes from each other.

Touch sensor having improved sensing sensitivity and display device including the same

A touch sensing unit includes driving electrode groups which are arranged in a first direction, each of the driving electrode groups including a plurality of driving electrodes electrically connected in a second direction intersecting the first direction, sensing electrode groups which are arranged in the second direction, each of the sensing electrode groups including plurality of sensing electrodes electrically connected in the first direction, driving lines which are connected to the driving electrode groups, respectively, a first sensing line group including sensing lines respectively connected to first sensing electrode groups among the sensing electrode groups, and a second sensing line group including sensing lines respectively connected to second sensing electrode groups among the sensing electrode groups. The sensing lines of the first sensing line group have the same width.
