To provide a structure body of a structure release that can extremely reduce the time required for an structure etching operation, can increase the throughput of an optical interference type display, and is appropriate to an optical interference type display cell structure, and its manufacturing method.

The optical interference type display cell structure includes a first electrode, a second electrode, and at least one support body. The second electrode 301 has at least one hole 306 and is disposed substantially parallel with the first electrode. The support body is positioned between the first electrode and second electrode, and a cavity 312 is formed. An etching agent is injected through a hole 306, a sacrificial layer existing between the first and second electrodes is etched to form the cavity.
