1. A method for making a spatial light modulator, comprising:

  • providing a first substrate that is transmissive to visible light;

    providing a second substrate having an array of circuitry and electrodes thereon;

    depositing a light absorbing layer on the first substrate to selectively block the passage of light through the first substrate;

    forming an array of deflectable reflective elements on the first or second substrate; and

    positioning the first and second substrates proximate to each other to form a substrate assembly.
