Abstract
A method for producing surface convexes and concaves enabling easy and highly precise formation of desired convex and concave shapes using a photomask is provided. A mask memberhaving light transmitting sections and non-light transmitting sections is disposed over one side of a photosensitive filmconsisting of a photosensitive resin composition with a light diffusing layerdisposed between the mask memberand the photosensitive film. Light is irradiated from a light source disposed on the side of the mask memberto expose the photosensitive filmthrough the light transmitting sections of the mask member, and exposed portions or unexposed portions of the photosensitive filmare removed by development to produce convexes and concaves on the photosensitive filmin shapes determined by shapes of the exposed portions or unexposed portions. In the light exposure, light exposure conditions such as haze of the light diffusing layerare controlled so as to control the shapes of the exposed portions or unexposed portions.
