This invention relates to a light valve ( 100 ) and a method for manufacturing the same. The light valve includes a substrate ( 10 ), a first comb-shaped electrode ( 40 ) and a second comb-shaped electrode ( 50 ). The substrate has a first through hole ( 13 ). The first comb-shaped electrode is formed on the substrate and has a number of first electrode teeth ( 42 ) and a hole portion ( 41 ) define a second through hole ( 44 ) configured for aligning with the first through hole. The second comb-shaped electrode has a number of second electrode teeth ( 52 ). The first and second electrode teeth are configured in a staggered fashion and at least one of the first and second comb-shaped electrodes is movable toward to the other.
