Abstract: The present disclosure provides a touch display device for minimizing viewing-angle-dependent variation in color coordinates. The touch display device includes a light-emitting element disposed in each of a plurality of subpixels including emission areas having different sizes, a plurality of touch electrodes disposed on the light-emitting element, and at least one opening formed in each of the plurality of touch electrodes. The width of the opening is formed differently in each of the plurality of subpixels including the emission areas having different sizes, thereby minimizing viewing-angle-dependent variation in color coordinates.
