Abstract: An organometallic compound represented by Chemical Formula I, and an organic light-emitting diode containing the same. In the Chemical Formula I, M may represent a central coordination metal, and includes one selected from a the group consisting of molybdenum (Mo), tungsten (W), rhenium (Re), ruthenium (Ru), osmium (Os), rhodium (Rh), iridium (Ir), palladium (Pd), platinum (Pt), and gold (Au). Each of R1 to R8 may independently represent one selected from the group consisting of hydrogen, deuterium, a substituted or unsubstituted C1 to C20 alkyl group, and a substituted or unsubstituted C3 to C20 bicycloalkyl group. A may represent a ring structure of isoquinoline. Each of X1 to X4 may independently represent one selected from CR11 and nitrogen (N).

Abstract: The present disclosure relates to an organic light emitting display device. According to an aspect of the present disclosure, an organic light emitting display device includes a plurality of sub-pixels including a first sub-pixel, a second sub-pixel and a third sub-pixel, a first electrode, a horizontal bank including a first horizontal bank and a second horizontal bank that are alternately arranged in a first direction to cover edges of the first electrodes, a vertical bank including a first vertical bank, a second vertical bank, and a third vertical bank that are alternately arranged in a second direction to cover edges of the first electrode and disposed on the horizontal bank, an organic light emitting layer and a second electrode. Wherein an area wider than the first sub-pixel is formed on the first horizontal bank or the second horizontal bank adjacent to the first sub-pixel, and ink is injected on the area, whereby color mixing of the ink can be minimized. And, a high-resolution organic light emitting display device can be implemented, simultaneously with improving display quality of the organic light emitting display device.
