Abstract:
A method of forming a hole transport layer in which an amount of ink per unit surface area to be applied to a plurality of groove regions is set so as to decrease in an order R, G, B. Prior to applying the ink, a nozzle head is scanned across while applying only solvent to each of the groove regions. At this time, an amount of the solvent to be applied to the groove regions is set so as to increase in the order R, G, B.
