PROBLEM TO BE SOLVED: To reduce unevenness of thickness in an organic light-emitting layer. SOLUTION: A hole injection layer 8b of an organic EL element 8 of an EL panel 1 can be formed by applying and coating a fluid body containing an organic material such as PEDOT/PSS on nearly a whole area of the top face of a substrate 10 before a bank 13 is formed, so that an adverse effect of creeping up can be alleviated as compared with a method of forming one by applying a fluid body on an opening 13a of the bank 13, and thickness unevenness of an organic light-emitting layer made by laminating a functional layer 8i and a light-emitting layer 8c on the hole injection layer 8b can be alleviated.
