Summary:An organic electroluminescent device is provided to prevent deflection of a metal mask in a specific region by arranging a divided spacer into zigzag shape on a substrate. An organic electroluminescent device comprises a plurality of sub pixels and a spacer(140). A plurality of sub pixels is arranged on a substrate into a matrix shape. The spacer is arranged between the sub pixels into a bar shape. Height of the spacer is 2.0um ~ 4.5um. A tapered angle(r) of the spacer is 25° ~80°. The spacer is divided on the same line. A divided spacer has the same length or has a different length. At least one among height, angle, and width of the spacer is changed according to a position of the substrate.
