Abstract

An electroluminescence display is disclosed that comprises: a pixel; a low-resistance line at one side of the pixel and having a connection part; an insulating layer on the low-resistance line; a low-resistance connecting terminal on the insulating layer and connected to the connection part; a passivation layer on the low-resistance connecting terminal; a planarization layer on the passivation layer; a cathode contact hole exposing a portion of the low-resistance connecting terminal. The low-resistance line includes an open area overlapping with a middle portion of the low-resistance connecting terminal at the connection part. The low-resistance connecting terminal connects to a first side and a second side of the low-resistance connecting terminal. The cathode electrode is connected to the low-resistance connecting terminal via the cathode contact hole.
