Abstract
An active matrix display device has pixels each with a light-sensitive device () for optical feedback functions. Each pixel has a light blocking structure () formed from the thin film layers of the display substrate in the proximity of the light-sensitive device () and substantially at the level of an input surface of the light sensitive device. This structure prevents the passage of light (g) to the light sensitive device from a substantially lateral direction.
