Light emitting display device

A light emitting display device comprising first to fourth anodes (120a, 120b, 120c, 120d) and a bank (195) exposing first to fourth light emitting portions (R, G, B1, B2) on a substrate (100). First and second light emitting layers (151, 152) are on the first and second anodes (120a, 120b), and a t...

Zusammenfassung:A light emitting display device comprising first to fourth anodes (120a, 120b, 120c, 120d) and a bank (195) exposing first to fourth light emitting portions (R, G, B1, B2) on a substrate (100). First and second light emitting layers (151, 152) are on the first and second anodes (120a, 120b), and a third light emitting layer (153) is on the third and fourth anode (120c, 120d). A first common layer (130) is on all four anodes. A charge generation layer (170) is on a fourth light emitting layer (180) in the fourth light emitting portion (B2). A second common layer (160) is on the first, second and third light emitting layers (151, 152, 153). The charge generation layer (170) and the fourth light emitting layer (180) is not on the third light emitting portion (B1). A cathode (190) is on the first to fourth light emitting layers.
