Abstract

An organic electroluminescent device (101) includes a substrate (110) including a plurality of pixel regions (P1, P2) each having a light emission region (EA) and an element region (DA); a plurality of thin film transistors (TFTs) including at least one switching TFT (Tr1) and at least one driving TFT (Tr2) in each element region (DA); a planarization layer (150) on the plurality of TFTs; a first electrode (160) on the planarization layer (150) and including first to third portions (160a - c)connected to one another, wherein the first (160a) and second portions (160b) are at each pixel region, and the third portion (160c) is at a neighboring pixel region; an organic light emitting layer (165) on the first electrode (160); and a second electrode (168) on the organic light emitting layer (165), wherein an end of the third portion (160c) overlaps the driving TFT (Tr2) of the neighboring pixel region.
