Abstract:
1. An organic EL light-emitting device comprising: a substrate having a color emission region, the color emission region having two or more pixel regions arranged in one row; linear main banks for defining the color emission region, the main banks opposing each other; a pixel isolation region arranged between each of the pixel regions in the color emission region; a pixel electrode arranged for each of the pixel regions; and an organic function layer arranged over the pixel electrode, wherein the pixel isolation region includes an auxiliary bank and a groove, the groove for making the pixel regions in communication with each other, and wherein, when the pixel regions includes a first pixel region, a second pixel region, and a third pixel region, the first, second and third pixel regions arranged consecutively; when the pixel isolation region between the first pixel region and the second pixel region is defined as pixel isolation region A, and the pixel isolation region between the second pixel region and the third pixel region is defined as pixel isolation region B; and when an end portion of the groove arranged in the pixel isolation region A at the second pixel region side is projected from the first pixel region to the second pixel region in a line direction of the main bank, the whole projection of the end portion overlaps the auxiliary bank in the pixel isolation region B.
