ABSTRACT:
Inside surround desiccant pattern A surrounding an organic EL element by bonding an element substrate to a sealing board, outside surround desiccant pattern C surrounding the inside surround desiccant pattern A, and internal desiccant pattern (having a thinner film thickness than the inside surround desiccant pattern A) surrounded by the inside surround desiccant pattern A are formed on the sealing board by one time screen printing. For this purpose, a screen mask is utilized on which opening patterns for the inside and outside surround desiccant patterns A, C and an opening pattern having a narrower opening width than the opening patterns for A and C for forming an internal desiccant pattern are formed. With this configuration, it has been achieved to manufacture a highly reliable organic EL display apparatus in more simplified process.
