17 Claims

1. A display device comprising:

a substrate including a display area and a non-display area adjacent to the display area, wherein the display area includes a first sub-display area including a plurality of light transmission areas and a second sub-display area adjacent to the first sub-display area;

a shield layer on the substrate;

an active layer on the shield layer;

a gate insulating layer on the active layer;

a gate electrode on the gate insulating layer;

an interlayer insulating film on the gate electrode;

a first source-drain electrode pattern on the interlayer insulating film;

a first planarization layer on the first source-drain electrode pattern;

a second source-drain electrode pattern disposed on the first planarization layer and electrically connected to the first source-drain electrode pattern through a contact hole in the first planarization layer;

a second planarization layer on the second source-drain electrode pattern;

an anode electrode disposed on the second planarization layer and electrically connected to the second source-drain electrode pattern through a contact hole in the second planarization layer;

a light emitting layer on the anode electrode;

a cathode electrode on the light emitting layer;

an encapsulation layer on the cathode electrode; and

a touch sensor disposed on the encapsulation layer and including a plurality of mesh-type touch electrodes,

wherein the plurality of touch electrodes includes a plurality of first touch electrodes disposed in a first touch area corresponding to the first sub-display area and a plurality of second touch electrodes disposed in a second touch area corresponding to the second sub-display area,

wherein a density of the plurality of first touch electrodes in the first touch area is lower than a density of the plurality of second touch electrodes in the second touch area, and

wherein the shield layer is overlapped with at least one of the gate electrode, the first source-drain electrode pattern, or the second source-drain electrode pattern.
