Claim 3:
4. A method of manufacturing the optical device of claim 1, comprising the steps of:
providing two substrates opposite to each other;
forming fine uneven layers having fine uneven shapes on opposing faces of the two substrates;
forming conductive layers to cover the fine uneven layers;
forming, by imprint, a partition wall structure configured to separate adjacent spaces, between opposing faces of the conductive layers; and
filling a fluid containing an electric field control material into the spaces separated by the partition wall, wherein
an average distance between unevennesses of the fine uneven layers is 50 to 300 nm and an average height of unevenness of the fine uneven layers is 30 nm or more.
