Abstract

PURPOSE: To prevent unevenness of distribution of transmitted light intensity and make positioning unnecessary, by radiating transmitted light from phase diffusion part to a photosensitivie layer spread on the phase diffusion part, exposing and developing it to form a light intensity compensating part.
CONSTITUTION: A phase diffusion plate 6 consists of a phase diffusion part 7 which works to vary the phase of light wave surface, and a light intensity compensating part 8 which is formed by exposing and developing by radiating transmitted light from the diffusion part 7 to a photosensitive layer 8a spread on this diffusion part 7. In this constitution, the photosenstive layer 8a, after development, indicates a reverse transmitted light intensity distribution to the transmitted light intensity distribution of a phase diffusion plate 1 which constitutes the diffusion part 7. By exposing and developing the photosensitive layer 8a while keeping the diffusion part 7 and compensating part 8 in an integral state, since the diffusion plate 6 is used for the original purpose without distrubing the configuration of the two parts, a smooth transmitted light intensity distribution may be obtained without requiring positioning.
