Organic EL display device and method for producing the same

摘要

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.

1. An organic EL display device, comprising:
a first substrate including a display area in which a plurality of pixels including an organic EL light-emitting layer are arrayed, the plurality of pixels each having a plurality of sub pixels; a second substrate that faces the first substrate and includes a plurality of opening areas each respectively located in correspondence with the plurality of sub pixels and a light-blocking area that demarcates the opening areas; a dam material provided between the first substrate and the second substrate so as to enclose the display area; and a filler material filling a space enclosed by the first substrate, the second substrate and the dam material; wherein: the light-blocking area includes an outer region and a center region; the outer region surrounds one pixel of the plurality of pixels; the center region is located inside the outer region and demarcates the opening areas; the filler material includes borders generated as a result of a plurality of portions of the filler material being fused together; and the borders of the filler material are located in an area corresponding to the outer region, and are not located in an area corresponding to the center region.
