Abstract
A method for producing surface convexes or concaves disposes a mask member having light transmitting sections and non-light transmitting sections over and spaced from one side of a photosensitive film including a photosensitive resin composition, and a light diffusing member is disposed on the opposite side of the photosensitive film across the mask member. Light is irradiated from a light source disposed on the opposite side of the mask member across the light diffusing member to subject the photosensitive film to light exposure through the light diffusing member and the light transmitting sections of the mask member. Exposed portions or unexposed portions of the photosensitive film are removed by development to produce convexes or concaves on the photosensitive film in shapes determined by shapes of the exposed portions or unexposed portions. In exposure, conditions such as haze of the light diffusing member are controlled to control the shapes of the exposed portions or unexposed portions.
