Abstract
A display device includes a plurality of emission areas that emit light, a plurality of touch electrodes disposed in a light blocking area surrounding the plurality of emission areas, in which the touch electrodes sense a touch, a first insulating layer disposed on the plurality of touch electrodes, and a plurality of light blocking parts disposed on the first insulating layer and overlapping the plurality of touch electrodes. A part of the plurality of light blocking parts includes a code pattern formed by an insertion portion inserted into the first insulating layer and overlapping the plurality of touch electrodes, and another part of the plurality of light blocking parts includes a non-code pattern formed by not having the insertion portion.
