Claim 0:
1. A touch detection device comprising:
touch driving lines on a first touch insulating layer;
touch detection lines on the first touch insulating layer in a touch detection area;
connection electrodes on the first touch insulating layer;
a second touch insulating layer on the touch detection lines and the connection electrodes;
driving electrodes disposed on the second touch insulating layer and connected to any one of touch driving lines;
detection electrodes disposed on the second touch insulating layer and connected to any one of the touch detection lines through a contact hole formed through the second touch insulating layers;
a third touch insulating layer formed on the second touch insulating layer on which the driving electrode and the detection electrode are disposed;
light emitting parts disposed under the touch detection area, and
a black matrix and color filters disposed on the third touch insulating layer,
wherein the detection electrodes are connected to the connection electrodes through a touch contact hole formed through the second touch insulating layer,
wherein the black matrix, the connection electrodes, the driving electrodes and the detection electrodes are formed in the mesh structure in a plan view,
wherein the black matrix overlaps partial areas of the touch detection lines, the driving electrodes, the detection electrodes, and the connection electrodes, and
wherein the color filters are disposed on the light emitting parts and are overlapped with the light emitting parts in the plan view.
