ELECTRO-OPTICAL BLOCKING DEVICE FOR AN ANTI-GLARE INCLUDING AT LEAST ONE PHOTO-SENSITIVE LAYER

摘要

The invention relates to an electro-optical blocking device (1000) including at least two first electrodes (1001, 1002) and at least a first cell including a layer of an electro-optical material, said first cell(s) being provided between said first electrodes, wherein each of said first cell(s) can be switched between at least on passing state, which it transmits a light beam, and at least one blocking state, in which it does not transmit the light beam, essentially based on the electric field applied t said first cell through the first electrodes. According to the invention, the blocking device also includes at least one solid layer of a first photo-sensitive material having a high transverse resistance and provided between said first electrodes.
