1. A spatial light modulator, comprising:
- a primary light reflective region;
an incidental light reflective region; and
a light-absorbing layer contacting at least a portion of the incidental light reflective region, the light-absorbing layer including;
a reflective first layer having a reflectivity greater than about 75%; and
a second layer connected to the reflective first layer, the second layer having a reflectivity less than about 75%.
