Abstract

A light emitting display device comprises: a substrate, an insulating layer, a planarization layer, a first anode electrode, a trench, a second anode electrode, an emission layer and a cathode electrode. The substrate has a first pixel and a second pixel. The insulating layer covers the first pixel and the second pixel on the substrate. The planarization layer is disposed on the insulating layer in the first pixel, and has a protrusion extruding upward. The first anode electrode is disposed on an upper surface of the protrusion of the planarization layer in the first pixel. The trench has a slit shape at a circumferential area of the second pixel by removing some portions of the insulating layer. The second anode electrode is disposed on the insulating layer in the second pixel. The emission layer is disposed on the first anode electrode and the second anode electrode. The cathode electrode is disposed on the emission layer.
