An electrophoretic display panel ( 1 ), for displaying pictures having a plurality of picture elements, has a plurality of pixels ( 2 ) and drive means ( 100 ). The pixels ( 2 ) have a first electrode ( 3 ) and a second electrode ( 4 ) for receiving a potential difference, and an electrophoretic medium ( 5 ) which is present between the first electrode ( 3 ) and the second electrode ( 4 ). The medium ( 5 ) has a first and a second extreme optical state and an intermediate optical state, intermediate between the first and the second extreme optical state. For the display panel ( 1 ) to be able to display a reproducible intermediate optical state, the drive means ( 100 ) are able to control, in operation, the potential difference for changing the optical state between the first extreme, the second extreme and a singular equilibrium optical state as the intermediate optical state, in dependence of the picture element to be displayed.
