摘要： 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.

摘要： A display device comprising a display unit that includes a plurality of light emitting areas; a plurality of touch electrodes that sense a touch and that are disposed between the plurality of light emitting areas; a plurality of code patterns that cover a portion of a front surface of at least one of the plurality of touch electrodes with a preset code shape; and an infrared scattering layer disposed on the plurality of touch electrodes and the plurality of code patterns according to an arrangement shape of the plurality of touch electrodes. The infrared scattering layer scatters infrared light incident on or reflected from the plurality of code patterns and the plurality of touch electrodes.
