Abstract
A light emitting display device includes first and second pixel circuit portions, each having a transistor with a polycrystalline semiconductor and a transistor with an oxide semiconductor, and first and second light emitting diodes including first and second anodes connected with the first and second pixel circuit portions, respectively. An encapsulation layer covers the first and second pixel circuit portions and the first and second light emitting diodes. A light blocking layer includes first and second light blocking layer openings that are disposed on the encapsulation layer and overlap the first and second anodes, respectively. First and second color filters are disposed in the first and second light blocking layer openings, wherein first and second expansion portions corresponding to the first and second anodes are disposed in a first and second conductive layers disposed first down from the first anode and second down from the second anode, respectively.
