<P>PROBLEM TO BE SOLVED: To suppress occurrence of ghost in an exposure head including a light shielding member having a light guide hole opened to an organic EL element with respect to a substrate having the organic EL element. <P>SOLUTION: The exposure head includes a light emitting substrate having the organic EL element, a supporting substrate having the light emitting substrate arranged in a first direction, a light shielding member having the light guide hole opened to the organic EL element, a lens for forming an image of the light emitted from the organic EL element and passing through the light guide hole, and a driving circuit for driving the organic EL element. When the light emitting substrate is viewed in a planar view through the light guide hole, the supporting substrate is shielded by the light emitting substrate, and the driving circuit has a region which is not shielded by the light shielding member. <P>COPYRIGHT: (C)2012,JPO&INPIT |
