Abstract
An organic electroluminescent device includes a substrate, a number of first electrodes disposed on the substrate, each of the first electrodes used to form a light-emitting unit; an insulative layer disposed on the substrate and used to define a pixel region of the light-emitting unit; a number of second electrodes disposed on the substrate, each of the second electrodes used to form a light-emitting unit, wherein the second electrodes are spaced apart from one another to form a number of isolation grooves each between two adjacent second electrodes.
