PROBLEM TO BE SOLVED: To provide an active matrix EL display device that can display a clear multi gray-scale color display by reducing the shift in the potential caused by potential drop due to the interconnect resistance of a power source supply line to decrease the unevenness in a display region. SOLUTION: A plurality of drawing-out ports of the power source supply line are arranged. Further, in the interconnect resistance between an external input terminal and a pixel portion power source supply line, potential compensation is performed by supplying potential to the power source supply line by a feedback amplifier. Further, in addition to the structure, the power source supply line may be arranged in a matrix. COPYRIGHT: (C)2011,JPO&INPIT |
