Abstract:
An exposure apparatus for exposing a photosensitive body comprising:a substrate, a convex lens disposed on said substrate, a semitransparent reflection layer disposed on said convex lens, and a pair of electrodes, and a light-emitting layer between said pair of electrodes, disposed on said semitransparent reflection layer, wherein said semitransparent reflection layer and said pair of electrodes and said light-emitting layer each has a curved shape corresponding to a curved shape of said convex lens, and a luminescent point of light is provided between said electrodes only inside a curved portion of said lens, and wherein one of said electrodes is a cathode and the portion of said apparatus between said cathode and said semitransparent layer constitutes a micro-resonator which limits wavelengths of light emitted from said light emitting layer so that a peak wavelength of the emitted light is disposed within a half-value width region of sensitivity of the photosensitive body.
