Abstract: A display panel of a display device includes emission areas and a non-emission area between adjacent ones of the emission areas. A sensing electrode is disposed on the non-emission area of the display panel. A light blocking member is disposed on a portion of the sensing electrode. The light blocking member absorbs light of a specific wavelength, and another portion of the sensing electrode that does not overlap with the light blocking member reflects light of the specific wavelength. When viewed on a plane, the light blocking member includes a first part and a second part having different line widths in a first direction.
