摘要：<P>PROBLEM TO BE SOLVED: To provide an electroluminescence display device capable of preventing a thin-film transistor from deteriorating, thereby improving image quality, and to provide a driving method thereof. <P>SOLUTION: The electroluminescence (EL) display device includes drive voltage supply lines; N compensation voltage supply lines; EL cells at each crossing of a plurality of data lines and a plurality of gate lines in a matrix form, wherein the EL cells emit light, in response to currents applied from the drive voltage supply lines; driving thin-film transistors (TFT), connected between the EL cells and compensation voltage supply lines that control the current applied to the EL cells; and a bias switch, connected in between the N-1th compensation voltage supply line and a control terminal of the driving TFT, connected to the Nth compensation voltage supply line that applies a bias voltage to the driving TFT, when a scan pulse is supplied to the (N-1)th gate line. <P>COPYRIGHT: (C)2005,JPO&NCIPI
