<p>PURPOSE: A light emitting device is provided to prevent non uniform brightness by preventing a voltage from dropping at a center portion of an electrode. CONSTITUTION: A first electrode(110) is formed on one side of a substrate. An auxiliary electrode(120) is formed on a first area on the top of a first electrode. An organic layer is formed on a second area of the top of the first electrode. A second electrode(140) is formed on an upper portion of the organic layer. A cut-out portion(150) is formed on either the first electrode or the second electrode.</p>
