Abstract: A touch sensor includes: a plurality of first sensor electrode columns disposed in a sensing area, the plurality of first sensor electrode columns each including one or more first sensor electrodes; a plurality of second sensor electrode columns alternately disposed with the first sensor electrode columns in the sensing area, the plurality of second sensor electrode columns each including a plurality of second sensor electrodes having a length defined by a longitudinal axis and a width extending in a direction across the length; and a plurality of lines connected to the first sensor electrode columns and the second sensor electrode columns. An outline length of at least some of the second sensor electrodes facing the first sensor electrodes varies along the longitudinal axis of its respective second sensor electrodes.

Abstract: A display device includes: a display panel including a display region including a rounded corner, the display region having a plurality of pixels arranged therein, and a non-display region surrounding the display region; a plurality of touch electrodes overlapping with the display region; and a first screen electrode disposed along the rounded corner to overlap with pixels disposed adjacent to the rounded corner among the plurality of pixels, the first screen electrode being electrically connected to some of the plurality of touch electrodes. Accordingly, the touch sensitivity of the touch electrodes can be improved, and pixels arranged in a stair step shape at the round corner of the display region can be prevented or reduced from being viewed from the outside.
