Abstract

An electroluminescence display includes a substrate including a display area and a non-display area, the non-display area disposed around the display area; a low potential pad disposed at the non-display area, and including a first electrode layer and a second electrode layer on the first electrode layer; a bank including a cathode contact hole exposing a middle portion of the low potential pad, and covering edge portions of the low potential pad; a mushroom structure element disposed at the middle portion of the low potential pad; an under-cut area formed at under edges of the bank and the mushroom structure element; a first cathode layer deposited on an upper surface of the bank and the mushroom structure element, an upper surface of the low potential pad exposed by the cathode contact hole and the under-cut area; a second cathode layer deposited on the first cathode layer excepting the under-cut area; and a third cathode layer contacting an upper surface of the second cathode layer, and the first cathode layer at the under-cut area.
