Abstract:
There are provided a light screening apparatus and a manufacturing method thereof. The light screening apparatus includes a substrate, a transparent electrode, a plurality of roll-up actuators and a plurality of light screening patterns. The substrate includes a light-transmitting region and the transparent electrode is formed on one surface of the substrate. Each roll-up actuator, which has opaque characteristics, is fixed on the circumference portion of the light-transmitting region and includes a fixing end and a moving part which extends from the fixing end. Gaps are formed between adjacent roll-up actuators, and the light screening patterns are formed on the substrate at locations corresponding to the gaps. The light-screening patterns prevent light incident through the gaps from being transmitted to the light-transmitting region.
