1. A display device comprising:
a substrate comprising a display area configured to display an image, wherein the display area comprises a first area capable of transmission and a second area different from the first area;
a transistor array in the display area over the substrate;
a plurality of light emitting elements positioned in each of the first area and the second area;
an encapsulation layer on the plurality of light emitting elements;
a touch sensor layer on the encapsulation layer, the touch sensor layer comprising a plurality of touch electrodes;
a polarizing plate on the touch sensor layer;
an optical transparent adhesive on the polarizing plate; and
a cover glass located on the optical transparent adhesive,
wherein at least one of the plurality of light emitting elements comprises:
an anode electrode layer on the transistor array;
a light emitting layer on the anode electrode layer; and
a heterogeneous cathode electrode layer on the light emitting layer,
wherein each of touch electrodes positioned in the first area among the plurality of touch electrodes comprises a mesh-type electrode having one or more openings,
wherein the polarizing plate comprises a first portion corresponding to the first area and a second portion corresponding to the second area, and
wherein the first portion has a higher transmittance than the second portion.
