Just some of the space behind the larger star will not receive light from the smaller star behind it. But that area will be illuminated by the bigger star, because.к. it, too, is giving off light, provided the star is not extinguished. But light from a smaller star can also get there by reflecting off other planets, comets, and other objects. A clear shadow would be if there were a planet instead of a bigger star, no matter the size, but what would the shadow be. The size of the shadow of course depends on the distance between the stars. If excluding the light of the larger star, there would be a shadow, but if with the light of the larger star. there shouldn't be a shadow.
