Abstract
Disclosed are an optical structure, and a camera module and an electronic device including the same. The optical structure includes a transparent substrate; a first moisture-proof layer disposed on the transparent substrate and including a first organic material having moisture-proof properties; and a first near-infrared absorbing layer disposed between the transparent substrate and the first moisture-proof layer and including a copper complex, wherein the first organic material having moisture-proof properties has a water vapor transmission rate (WVTR) of less than or equal to about 100 g/m2/day measured at a thickness of 100 μm.
