Description

technical field [0001] The invention relates to an organic electroluminescent display device, a method for manufacturing the organic electroluminescent display device, a large-scale organic electroluminescent display device and electronic equipment. Background technique [0002] In recent years, display panels using organic electroluminescent elements (hereinafter, referred to as organic EL elements) can realize high-quality display by driving the organic EL elements with thin film transistors (hereinafter, referred to as TFTs). In particular, a display panel using an organic EL element, since the organic EL element is a solid element, is easier to seal the end face of the display panel than a display panel using a liquid crystal, and is suitable for arranging a plurality of display panels in parallel for large-scale Tiling (tiling) technology. [0003] When performing the above-mentioned tiling of the display panel, it is difficult to secure a position for mounting a drive...

AI Technical Summary

Problems solved by technology

In the aforementioned Patent Document 1, although a polyimide substrate is used as one of the substrates, the polyimide substrate has a problem of insufficient gas barrier, and there is a risk of damage to the organic EL element.

[0008] In addition, if a glass substrate or other substrate having a thermal expansion coefficient different from that of the polyimide substrate is used as the other substrate, the sealability of the display panel may be damaged due to the difference in thermal expansion coefficient of each substrate, and the organic EL element may be damaged.

[0009] In addition, even if a glass substrate with barrier properties is used as one of the above-mentioned substrates, it is difficult to form a large number of through holes on the glass substrate in the prior art, and there is a problem that it takes a long time to form them.
