    • PROBLEM TO BE SOLVED: To provide a pattern exposure method capable of reducing generation of moire, and to provide a method for producing a conductive film and a conductive film. SOLUTION: The conductive film 10 is obtained by subjecting a photosensitive material to proximity exposure through a photomask disposed away from the photosensitive material via a proximity gap of 70 to 200 μm, and transferring the mask pattern onto the photosensitive material as a periodical pattern periodical in a conveyance direction. The conductive film 10 has a conductive portion 12 composed of a plurality of conductive metal thin wires and a plurality of openings 14, wherein side portions of a first metal thin wire 12a and of a second metal thin wire 12b are shaped to have protruding portions 26, which protrude toward the openings 14 from virtual lines m representing a design width Wc of the first metal thin wire 12a and of the second metal thin wire 12b, and have a protrusion amount of 1/25 to 1/6 of the design width Wc.

    • PROBLEM TO BE SOLVED: To improve the efficiency of exposure processing by simultaneously forming two kinds of exposure patterns having different required resolutions from each other in the same exposure step. SOLUTION: An exposure pattern is formed on a TFT substrate 8 coping with a plurality of mask patterns formed on a photomask 3 by intermittently irradiating the TFT substrate 8 through the photomask 3 with light 24 from a light source while conveying the TFT substrate 8 in one direction. The photomask 3 has an electrode wiring pattern 14 and a signal wiring pattern 17 in different required resolving powers from each other, formed on one surface of the mask such that an electrode wiring pattern group 16 comprising a plurality of electrode wiring patterns 14 and a signal wiring pattern group 18 comprising a plurality of signal wiring patterns 17 are sequentially formed along a conveying direction of the TFT substrate 8. On the other surface of the photomask, a microlens 19 that reduces and projects the electrode wiring pattern 14 having a high required resolving powder onto the TFT substrate 8 is formed coping with the electrode wiring pattern. The photomask is disposed with the microlens 19 side close to the TFT substrate 8. COPYRIGHT: (C)2010,JPO&INPIT
