PURPOSE: An active organic EL device and a method for manufacturing the same are provided to reduce crosstalk between neighboring pixels by forming electrodes for BM at non-emitting region. CONSTITUTION: An active matrix type EL device comprises a substrate(1) having a plurality of pixels; a driving element including a gate electrode, an active layer, a source electrode, and a drain electrode; a first electrode connected to the drain electrode; an insulating layer(3) formed on the non-emitting region of the first electrode; an electrode(4) for BM formed on the insulating layer; a second electrode connected electrically to the electrode for BM; and an organic thin film(5) disposed between the first electrode and the second electrode and emitting light by electric field. 본 발명은 비발광 부분에 BM겸용 전극을 형성하여 이를 전기적으로 캐소드 전극과 접속하여 인접 화소간의 크로스토크 효과를 줄일 수 있는 능동 유기 전계 발광 소자 그 제조방법을 제공한다. 이를 통해, 발광된 빛의 칼라 크로스 토크를 억제하고 콘트라스트를 증가시킴으로써, 고정세, 고효율, 고휘도를 구현할 수 있다.
