Abstract
A display capable of preventing an emission layer from deterioration resulting from temperature rise of an electrode also when the same is increased in size and easily connectable with an external current source also when the same is connected with the external current source on a single portion is provided. This display comprises a first electrode formed on a substrate, an emission layer formed on the first electrode, a second electrode formed on the emission layer, a peripheral electrode, arranged to enclose the outer periphery of the second electrode and connected with at least three edges of the outer periphery of the second electrode, having a smaller sheet resistance value than the second electrode, and a current source connection terminal connected to the outer periphery of the peripheral electrode. Thus, current readily flows from the second electrode toward the peripheral electrode, while the current can be dispersedly fed along three or four directions.
