Abstract
A method for manufacturing a display device includes the step of forming a preset basic pattern in a plurality of places on an insulation substrate by exposing and developing a photosensitive material film which is formed on the insulation substrate, wherein the exposure is performed using a direct writing exposure device. The exposure is performed using the direct writing exposure device in which the light quantity distribution of the pattern of light formed by the spatial optical modulating element is corrected such that a fluctuation quantity of a size of the basic pattern formed in the plurality of places becomes not more than 0.2 μm.
