Patent ID: 8118383

Claim:
A pattern forming method comprising the step of ejecting droplets of a liquid containing a functional component, from nozzles of an inkjet recording head onto a surface of a substrate in one direction in sequence so as to form a linear pattern on the surface of the substrate, wherein: the inkjet recording head is controlled in such a manner that p ≤ π ⁢ ⁢ d 6 ⁢ ( θ sin 2 ⁢ θ - cos ⁢ ⁢ θ sin ⁢ ⁢ θ ) ⁢ { tan ⁢ θ 2 ⁢ ( 3 + tan 2 ⁢ θ 2 ) } - 2 3 is satisfied where d denotes a diameter of the droplets of the liquid before depositing on the surface of the substrate, θ denotes a contact angle of the droplets of the liquid with respect to the substrate, and p denotes a dot pitch of the droplets of the liquid that are adjacently deposited on the surface of the substrate, and the droplets of the liquid contain a volatile solvent with volume ratio not less than [ 1 - 6 ⁢ p ⁡ ( θ sin 2 ⁢ θ - cos ⁢ ⁢ θ sin ⁢ ⁢ θ ) ⁢ { tan ⁢ θ 2 ⁢ ( 3 + tan 2 ⁢ θ 2 ) } - 2 3 π ⁢ ⁢ d ] × 100 ⁢ % .
