Claim 11:
12. A manufacturing method of an organic light emitting diode display device including a touch sensor, the manufacturing method comprising:
providing a plurality of light emitting elements in a plurality of light emitting areas on a substrate;
providing a first encapsulation film covering the plurality of light emitting elements;
providing a bridge electrode on the first encapsulation film;
providing a bank insulating film on the first encapsulation film, the bank insulating film exposing a part of the bridge electrode;
providing a plurality of color filters each on the first encapsulation film;
providing a planarization film to cover the plurality of color filters and the bank insulating film;
providing a touch electrode on the bank insulating film to be vertically overlapped with the bridge electrode; and
providing a second encapsulation film covering the touch electrode and the planarization film,
wherein the providing of the touch electrode includes providing a touch line together along a side surface of the planarization film,
wherein the providing of the bank insulating film on the first encapsulation film includes providing a plurality of trenches exposing a portion of an upper surface of the first encapsulation film, corresponding to the plurality of light emitting areas,
wherein the plurality of color filters are formed by filling the plurality of trenches with a pigment in an inkjet method and curing the pigment,
wherein a lowermost surface of each of the plurality of bridge electrodes directly contacts an uppermost surface of the first encapsulation film, a lowermost surface of the bank insulating film directly contacts the uppermost surface of the first encapsulation film, and a lowermost surface of each of the plurality of color filters directly contacts the uppermost surface of the first encapsulation film,
wherein the bridge electrode is disposed between the touch electrode and the first encapsulation film, the bridge electrode is disposed under a concave portion of the touch electrode and directly contacts a lower surface of the concave portion, and a point of contact between the concave portion of the corresponding touch electrode and a corresponding bridge electrode among the plurality of bridge electrodes is disposed in a corresponding trench in the bank insulating film between two adjacent color filters among the plurality of color filters,
wherein the providing of the touch electrode includes connecting the bridge electrode and the touch electrode to each other by providing a contact on the bridge electrode exposed by the bank insulating film and providing the touch electrode on the bank insulating film, and
wherein the bridge electrode and the touch electrode vertically overlapped with the bridge electrode and connected to the bridge electrode through the contact do not vertically overlap the plurality of the light emitting areas.
