Claim:
1. A pixel matrix electro-optical device, having a first and a second conducting plane supplying a first and a second supply voltage to each pixel of the matrix, the first conducting plane being rectangular and supplied mainly via two adjacent edges, wherein the power supply to the first conducting plane at least is provided from a series of individual voltage sources distributed along each of the two adjacent edges, the voltage sources being adapted to apply different respective voltages to a series of contact points provided on each of the two adjacent edges of the plane, and in that the voltages applied to these contact points by the voltage sources vary in a monotonic manner between a first value at a first contact point at the end near the junction between the two adjacent edges and a second value at a final point at the other end of each of the edges, with a monotonically increasing variation for a power conducting plane that supplies current or a monotonically decreasing variation for a power conducting plane that draws current.
