Abstract:
A light emitting display device includes a lower substrate, a thin film transistor on the lower substrate, a passivation layer disposed on the thin film transistor and including hydrogen, an overcoating layer disposed on the passivation layer and planarizing the passivation layer, a light emitting element disposed on the overcoating layer and including an anode, a light emitting layer on the anode, and a cathode on the light emitting layer, a bank disposed on the overcoating layer and defining a light emitting area, an adhesive layer on the light emitting element and the bank, and a hydrogen absorbing layer disposed on the adhesive layer and including a hydrogen absorbing filler, wherein a side end of the bank is disposed more inwardly than side ends of the adhesive layer and the hydrogen absorbing layer, wherein the side ends of the adhesive layer and the hydrogen absorbing layer are disposed more inwardly than a side end of the overcoating layer.
