Production apparatus and production method of light emitting device

An apparatus for manufacturing a light emitting device provided with a plurality of light emitting elements arranged on a substrate, comprising:

• a rotating plate cylinder provided with a flexographic plate printing ink that forms an organic layer of the light emitting elements on the substrate;
• first and second intermediate transfer members that contact the flexographic plate to transfer the ink;
• a head unit that supplies the ink to the first and second intermediate transfer members,
• a storage unit that stores as ink replenishment patterns regions in which the ink is removed from the intermediate transfer members by the transfer of the ink from the intermediate transfer members to the flexographic plate;
• a control unit that supplies the ink from the head unit to the regions of the ink replenishment patterns on the surfaces of the intermediate transfer members;
• an intermediate transfer medium movement device that alternately moves the first and second intermediate transfer members so that one of the intermediate transfer members is at a position where one of the intermediate transfer members is related to the transfer of the ink from the intermediate transfer members to the flexographic plate and the other one of the intermediate transfer members is at a position where the other one of the intermediate transfer members is related to maintenance;
• and
• a cleaning device that cleans the other one of the intermediate transfer members that is at the position where the other one of the intermediate transfer members is related to the maintenance.

• an intermediate transfer member that contacts the flexographic plate to transfer the ink;
• a head unit that supplies the ink to the intermediate transfer member;
• a storage unit that stores an ink supply pattern on a surface of the intermediate transfer member as a printing pattern to be printed on the substrate;
• and
• a control unit that supplies the ink from the head unit to a region of the ink supply pattern of the intermediate transfer member.

A manufacturing method of a light emitting device provided with light emitting elements, the method comprising:

• supplying an ink containing a material of an organic layer of the light emitting elements to an intermediate transfer member, and forming an ink film on the surface of the intermediate transfer member;
• transferring the ink film from the intermediate transfer member to a flexographic plate;
• and
• printing on a substrate the ink film transferred to the flexographic plate, wherein an inkjet head selectively replenishes the ink to a region to which the ink has been moved from the intermediate transfer member by the transfer, and reforms the ink film on a surface of the intermediate transfer member.

A manufacturing method of a light emitting device provided with light emitting elements, the method comprising:

• selectively supplying an ink containing a material of an organic layer of the light emitting elements to a region, on a surface of an intermediate transfer member, that is to contact a flexographic plate of a plate cylinder in use of an inkjet method;
• transferring the ink from the intermediate transfer member to the flexographic plate of the plate cylinder;
• and
• printing on a substrate the ink from the plate cylinder.
