Abstract
A display device (1) has a display panel (2) which comprises a first substrate (6) on which a first picture electrode (11-27) is provided as well as a substantially parallel second substrate (7) on which a second picture electrode (20) is provided, both substrates (6, 7) sandwiching an electro-optical medium (8). Said electro-optical medium (8) is capable of switching between an at least substantially transparent state and a scattering state under the influence of an electric field. A transparent insulating layer (10) is provided between the first picture electrode (11-17) and the electro-optical medium (8), said insulating layer reflecting the light (30) which, at least during operation, is emitted by a light source (3) and sidelong captured by the panel (2), so that it does not reach the first picture electrode (11-17).
