Abstract: PROBLEM TO BE SOLVED: To provide a technical method which separates pixels simply in a device that forms a fine structure by means of mold transfer and makes movement by pixel unit. SOLUTION: On a transfer mold 70 to be used to form an optical element 3 as a pixel, a face 72 which regulates a surface 3a of the optical element 3 and a projection 74 for separation capable of forming a clearance 47 for separating by pixel unit are arranged. Therefore, when the transfer mold 70 is removed, the upper face of the optical element 3 is formed and at the same time the clearance 47 for separation is formed also. So, an etching process for forming the clearance 47 for separating by pixel unit can be omitted, and the fine structure which needs high dimensional accuracy can be produced highly accurately and simply.
