Summary:The present invention relates to a high-resolution organic electroluminescence display device. The organic electroluminescence display device comprises: a first substrate including a pixel region including a plurality of red, green, and blue (RGB) subpixels, and a dummy pixel region including a plurality of RGB dummy subpixels; a plurality of first bank layers disposed in the pixel region in a first direction and a second direction to define a plurality of subpixels; a plurality of second bank layers disposed on the first bank layers in the first direction in the pixel region to partition boundaries between RGB subpixel columns; an organic light-emitting element formed on each of the subpixels; and a third bank layer formed between the RGB dummy subpixels in the dummy pixel region to form at least one first drop region in which an organic light-emitting material is dropped. According to the present invention, a rapid process is possible by forming an organic light-emitting layer by a coating process. 본 발명은 고해상도 유기전계발광 표시장치에 관한 것으로, 복수의 R(Red),G(Green),B(Blue) 서브화소를 포함하는 화소영역 및 복수의 R,G,B 더미서브화소를 포함하는 더미화소영역을 포함하는 제1기판; 상기 화소영역에 제1방향 및 제2방향을 따라 배치되어 복수의 서브화소를 정의하는 복수의 제1뱅크층; 상기 화소영역에 제1방향을 따라 상기 제1뱅크층 위에 배치되어 R,G,B 서브화소열 사이를 구획하는 복수의 제2뱅크층; 상기 서브화소에 각각 형성되는 유기발광소자; 및 상기 더미화소영역 내의 R,G,B 더미서브화소 사이에 형성되어 유기발광물질이 적하되는 적어도 하나의 제1적하영역을 형성하는 제3뱅크층으로 구성된다.
