Abstract

A light emitting display device including a substrate (110) including a plurality of pixels (P); a planarization layer (PL) on the substrate (110) and having a first portion (PL1) surrounding a plurality of pillar-shaped second portions (PL2); an anode electrode (ANO) on the planarization layer (PL); an emission layer (EL) on the anode electrode (ANO); and a cathode electrode (CAT) on the emission layer (EL). Further, the pillar-shaped second portions (PL2) of the planarization layer (PL) have a refractive index corresponding to a refractive index of the cathode electrode (CAT) such that light transmitted by the emission layer (EL) is reflected within a corresponding pillar towards the substrate (110), and the refractive index of the pillar-shaped second portions (PL2) is greater than a refractive index of the first portion (PL1).
