More Information
Summary:A light emitting display apparatus includes a substrate including a plurality of sub-pixels; an overcoating layer on the substrate and having a base portion and a protrusion portion; a first electrode disposed to cover a side portion of the protrusion portion and the base portion at the plurality of sub-pixels; a bank layer covering a portion of the first electrode and the overcoating layer; and a light emitting layer and a second electrode on the first electrode and the bank layer at the plurality of sub-pixels. The first electrode includes a reflective layer and a transparent conductive layer on the reflective layer, the transparent conductive layer includes a first portion on the base portion and a second portion on a side surface of the protrusion portion, and a thickness of the second portion is greater than a thickness of the first portion.
