Abstract: A light emitting display device includes: a substrate; a semiconductor layer disposed on the substrate; a first insulating layer disposed on the semiconductor layer; a first gate conductor disposed on the first insulating layer; a second insulating layer disposed on the first gate conductor; a second gate conductor disposed on the second insulating layer; an interlayer insulating layer disposed on the second gate conductor; a data conductor disposed on the interlayer insulating layer; a passivation layer disposed on the data conductor; a diode first electrode disposed on the passivation layer; a partition wall disposed on the diode first electrode and including an opening overlapping the diode first electrode; a light emitting layer; and a diode second electrode. The data conductor includes a first inclined surface and a second inclined surface, and an area of the first inclined surface is different from an area of the second inclined surface.
