Abstract

Official abstract text for this publication.

There is provided an active matrix EL display device that can display a clear multi gray-scale color display to reduce the shift in the potential caused by the potential drop due to the wiring resistance of a power source supply line, in order to decrease the unevenness in a display region. A plurality of drawing out ports of the power source supply line are arranged. Further, in the wiring resistance between the external input terminal and the 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 above structure, the power source supply line may be arranged in a matrix.

First claim

Opening claim text (preview).

What is claimed is: 1. A display device comprising: a plurality of power supply lines comprising a plurality of first power supply lines disposed in a direction parallel to a source signal line and a plurality of second power supply lines disposed in a direction perpendicular to the source signal line; and a pixel electrode, wherein the plurality of power supply lines comprises a first wiring and a second wiring, wherein the first wiring is over a first insulating film forme…
