Patent number: 9530985Abstract: A method includes: forming, in a first substrate, a display area in which a plurality of pixels including an organic EL light-emitting layer are arrayed; forming, in a second substrate, a plurality of opening areas respectively located in correspondence with the plurality of pixels and a light-blocking area that demarcates the plurality of opening areas; providing a dam material such that the dam material encloses the display area; dripping a filler material to an area enclosed by the dam material; and attaching the first substrate and the second substrate to each other, and fusing together dripped portions of the filler material, thereby bonding the both substrates to each other. The both substrates are attached to each other while being positionally aligned such that borders between the dripped portions of the filler material that is generated by the fusion are located in an area corresponding to the light-blocking area.Type: GrantFiled: May 25, 2016Date of Patent: December 27, 2016Assignee: Japan Display Inc.Inventors: Tetsuya Nagata, Takumi Kuji
