Abstract

A display device includes a pixel in a display area, sensing electrodes overlapping the pixel, a sensing pad in a non-display area, a sensing connection line in the non-display area, and electrically connected to the sensing pad, a sensing signal line in the non-display area, and electrically connected to the sensing electrodes, and a power line extending from the non-display area, and electrically connected to the pixel, wherein the sensing signal line is electrically connected to the sensing connection line through an opening or indentation defined by the power line.

Claims (45)

1. A display device comprising:

a pixel in a display area;

sensing electrodes overlapping the pixel;

a sensing pad in a non-display area;

a sensing connection line in the non-display area, and electrically connected to the sensing pad;
