Our main purpose is to study ampleness and positivity properties of the direct image &phi;{\bigstar}<I>L</I> of a holomorphic line bundle <I>L</I> under a smooth morphism &phi;: <I>X</I>&rarr;<I>Y</I> between compact complex analytic manifolds. We show that in general the ampleness of <I>L</I> does not imply that of the direct image &phi;{\bigstar}<I>L</I> but only that of the direct image of the adjoint line bundle &phi;{\bigstar}(<I>K</I><SUB><I>X</I>/<I>Y</I></SUB>&otimes;<I>L</I>).
