Abstract
A display device having a transparent supporting plate which is provided with transflective regions. At a short distance from the first supporting plate resilient electrodes are connected which are manufactured from a partially reflective material. By varying the distance between the resilient electrodes and the transflective regions, the reflection of incident light can be controlled from zero to maximum intensity as a result of the occurring interference. Both monocolor and multicolor pictures can be displayed by means of such a display device. Such a display device is particularly suitable for use in a projection television device.
