Electronic modulating device

An electronic modulating device, comprising:

• a first substrate comprising a first portion and a second portion;
• a second substrate disposed opposite to the first substrate;
• at least one working device disposed between the first substrate and the second substrate, wherein the at least one working device overlaps the first portion and does not overlap the second portion;
• a first adjustment unit disposed between the first portion of the first substrate and the second substrate, wherein the first adjustment unit has a first thickness;
• a second adjustment unit disposed between the second portion of the first substrate and the second substrate, wherein the second adjustment unit has a second thickness;
• and
• a plurality of third adjustment units disposed between the first substrate and the second substrate, wherein the first adjustment unit is disposed between two of the plurality of third adjustment units, and the second adjustment unit is disposed between another two of the plurality of third adjustment units, wherein at least one of the plurality of third adjustment units has a third thickness;
• wherein the first thickness is different from the second thickness, and the third thickness is less than the first thickness.
