Claim 18:
19. A manufacturing method of a light emitting display device, the manufacturing method comprising: in a display area of a substrate, forming a transistor including a source electrode and a drain electrode; forming a lower planarization layer on the transistor; forming a light emitting diode on the lower planarization layer; forming an encapsulation layer on the light emitting diode; forming sensing electrodes on the encapsulation layer; forming a first color filter on the sensing electrodes; forming a light blocking part on the first color filter; forming a second color filter on the light blocking part; forming a third color filter on the second color filter; and forming an upper planarization layer on the third color filter; in a non-display area of the substrate, forming a lower pad electrode disposed on a same layer as the source electrode and the drain electrode; forming an upper pad electrode disposed on a same layer as the sensing electrodes, the upper pad electrode being disposed on the lower pad electrode; and forming a covering layer that is in contact with a side surface part of the upper pad electrode and disposed between the upper pad electrode and an adjacent upper pad electrode, the side surface part of the upper pad electrode being disposed on the lower planarization layer, wherein the covering layer includes the first color filter, and wherein the upper pad electrode includes: an upper layer; a middle layer; and a lower layer, wherein the covering layer is in contact with the side surface portion of the upper pad electrode at the middle layer.
