Patent ID: 8778576

Claim:
An exposure method for forming, while conveying, in a first direction, a substrate having a light blocking layer formed in a grid-like shape, colored pixels of a color filter on the substrate, wherein a photomask having a plurality of openings, and the substrate having a resist applied thereto are positioned so as to be opposed to a blinking light source that repeatedly emits light and emits no light, the blinking light source is caused to blink while the substrate is being continuously conveyed in the first direction, to intermittently perform multiple exposures, the photomask is moved in a second direction orthogonal to the first direction, to perform alignment between the photomask and the substrate, in each exposure, intervals at which the blinking light source blinks are controlled in each exposure such that a portion of the plurality of openings of the photomask overlaps a portion of exposed patterns having been obtained through the plurality of openings of the photomask by an immediately preceding exposure, and a difference between a width of each opening of the photomask in the first direction, and a width, in the first direction, of one opening region surrounded by the light blocking layer is greater than a difference between a width of each opening of the photomask in the second direction, and a width, in the second direction, of one opening region surrounded by the light blocking layer.
