The electro-optical display device has a translucent front wall ( 12 ) and at least one pixel ( 10 ) with an electro-optical medium, a scattering medium ( 14 ) and a switching electrode ( 6 ) associated with the front wall ( 12 ), and drive means via which the pixel ( 10 ) can be brought to different optical states. According to the invention, the pixel ( 10 ) comprises a low-refractive index C material ( 21 ) with a refractive index nt in the range from 1.0<=1.4.4. Preferably, the low-refractive index material ( 21 ) is provided between the switching electrode ( 6 ) and the electro-optical medium. Preferably, the electro-optical medium is an electro-phoretic medium or an electro-chromic medium. The electro-optical display device combines a high brightness with a wide viewing angle.
