PROBLEM TO BE SOLVED: To provide a method to suppress or decrease overflowing of ink from a recessed part which is an adaptable method for the manufacture of a panel for a display device by supplying a liquid from a liquid injection head to recesses on a substrate. SOLUTION: The liquid is supplied in such a manner that the volume V of the liquid to be supplied to the recessed part on the substrate satisfies the relation of formula (1). In formula (1), V is the volume [m3] to be supplied to the recessed part, θ is the contact angle [rad] of the liquid to a barrier wall member, W is the length [m] of the recessed part in the direction perpendicular to the longitudinal direction, L is the length [m] of the recessed part in the longitudinal direction and H is the depth [m] of the recessed part.
