Abstract
A display arrangement (LCD etc.) in which the control voltage range is enlarged by including in the control lines (13.sup.a, 13.sup.b) additional diodes (14) which are connected to a common point (15). In order to counteract a capacitive by-effect, additional diodes (17) are connected in parallel with opposite polarity. The enlarged control range provides a wider choice of LCD material or other electrooptical materials.
