<p>A matrix display device, suitable for displaying TV pictures, has a plurality of display elements (20) arranged in a matrix array and defined by electrodes (33 and 41) on opposing substrates with, for example, liquid crystal material (32) therebetween and with the display elements being individually controllable via switching elements (40) such as thin film transistors. Each display element is sub-divided into a plurality of sub-elements using a plurality of sub-electrodes (55) on one substrate which are each connected via a series capacitor (CX) to a switching element, the ratio of capacitances of the sub-elements to their respective series capacitors differing from one another. As applied voltage is increased, progressively more sub-elements are caused to change state providing in effect various grey scale levels. Display materials having comparatively sharp switching characteristics can be used.</p> |
