Kind Code:

A

Abstract:

To provide a method for manufacturing a small optical element which can suppress a defective shape caused by partial stripping from a molding die and can attain higher accuracy and to provide a small optical element, a display element having the small optical element, a display device, an image pickup element and an image pickup device.

In the manufacturing method of small optical element by using the molding die, uniting an optical energy curable resin onto a glass substrate and forming a small optical element or the small optical element, when the height of a small convex part formed by the resin is defined as H1 and the height of a flat part formed by the resin is defined as H2, the small optical element is formed so as to satisfy the relation of H2 > H1/5.
