Patent ID: 8339560

Claim:
A method for manufacturing a display device comprising 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 of the photosensitive material film is performed using a direct writing exposure device in such a manner that an exposure object area is divided into a plurality of small areas, the whole exposure object area is exposed by performing the exposure for every small area, and a pattern of light to be radiated to each small area is formed by performing a numerical control of a spatial optical modulating element, wherein the exposure of the photosensitive material film 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.
