Patent ID: 8679380

Claim:
A lens forming method comprising the steps of: interposing an uncured resin between a lens molding plate and a flat-shaped transparent substrate that are disposed to face each other with a distance in between for an opening, the lens molding plate having a plurality of lens-curved surface parts; and performing light irradiation on the resin interposed between the lens molding plate and the transparent substrate so that curing of the resin advances from the plurality of lens curved-surface parts on the lens molding plate toward a periphery thereof, wherein, the step of performing light irradiation includes irradiating each lens curved-surface part on the lens molding plate with an amount of light larger than an amount of light with which a periphery of each lens curved-surface part is irradiated by using a lens array having a plurality of condenser lenses, the light irradiation being performed in a single stage.
